SPRAYER SETUP FOR TOBACCO FUMIGATION

SPRAYER SETUP FOR SPECIALISED APPLICATIONS IN TOBACCO

Here's an example of a complete layout for tobacco land fumigation prior to planting. The fumigants such as EDB - 1,2 dibromoethane or Telone^® - 1,3 dichloropropene are used with this system.   These products are particularly aggressive so the materials in contact with these spray accessories have to be carefully selected. Telone is applied as the concentrate and cannot be diluted with water. If using an old fumigant product like metham sodium, the brass regulator cannot be used.

The fumigant is fed into the pipes behind the tines on the implement and incorporated into the soil. It is not sprayed into the soil under pressure. An orifice plate is placed into each line to accurately meter the amount needed.

Take note of all the adaptors and hose-shanks required. We provide the entire system ready to use including the tubing.

The real world. A bit different to the promo pamphlets!

We are way beyond the accessories supply business - we're in the information business.

Telone is a registered tradename of the Dow AgroSciences organisation.

FILTERS IN-LINE - How to use and maintain.

IN-LINE FILTER - What's inside and how to use and maintain it.

This flush-out filter type is placed in-line between the supply tank and a positive displacement pump. It can also be placed in-line after a centrifugal pump. Sizes from 3/4" to 1 1/2" are rated to 14 bar 1400 kPa or 200 psi.

Only 3 of the filter elements are shown: Red 50 mesh while the Blue is 80 mesh and the Green element 100 mesh.

Ensure that the suction size of the pump matches or is smaller than the filter connections. EXAMPLE: If the pump has a 32 mm or 1 1/4" suction or inlet then use an in-line filter with 32 mm or bigger connections.

Leaking? A common fault when the bowl leaks is to overtighten it. The square profile o-ring in the head needs replacement. It's a tight fit and make sure it is flush and square with the head.

Cleaning and reassembly: After cleaning the filter element, always push it into the filter head before screwing on the bowl. If you don't,   this is what happens. 

The end is crushed and the dirt gets through to the pump valves and the nozzle-tips.

THE 6815 PRESSURE REGULATING / RELIEF VALVE - What's inside and how it works.

THE 6815 PRESSURE REGULATING / RELIEF VALVE - What's inside and how it works.

Here's a simple sprayer layout using a positive displacement pump. Unlike a centrifugal pump the positive displacement pump draws in a specific volume on its suction or supply side with each revolution and pushes out that volume to the pressure or demand side. Any excess has to go somewhere or else the pump or a pipe will pack up. That's why the PRV - Pressure Relief Valve is in-line to return this excess to the tank via the bypass line.

THE PUMP PUTS OUT A SPECIFIC VOLUME WITH EACH REVOLUTION AND IT'S THE NOZZLE-TIP THAT SETS THE PRESSURE. IT SHOULD BE CLEAR THAT IF THE NOZZLE-TIPS TOTAL VOLUME EXCEEDS THE PUMP'S CAPACITY, THE PRESSURE WILL BE ZERO.

Here's a image showing the innards of the PRV. To the right a spring set, plunger and inlet for the 300 psi or 20 bar unit. The brass inlet illustrated is a 3/4" unit. The seal at the top merely prevents the spray-mix from getting past the adjusting T-screw.

To the left of the image is a spring, stainless steel plunger and hardened stainless steel inlet for the 1200 psi or 80 bar PRV. Note this inlet has 1/2" thread.

As you compress the spring and put increasing tension on the plunger,  more liquid is forced through the nozzles. The excess is forced past the plunger and returned to the tank via the bypass line.

CALIBRATION LESSON 4 - How much product to put into the tank.

CALIBRATION - Lesson 4 CALCULATING HOW MUCH TO PUT INTO THE TANK.

Well you've found the right nozzle tip and for the moment let's assume you bought them from Chemicon.

The final bit of information relates to the spray-tank and how much product to put into the tank.

In our example we mentioned a boomsprayer with a 600 litre tank. The farmer wanted to spray at 100 l/ha so how many hectares can be sprayed with a tank. CALCULATE: 600 litre tank divided by 100 l/ha = 6 hectares. OR ha's that can be sprayed with 600 litre tank is 600/100=6 ha.

If the label specifies a rate of 6 litres per hectare then you need to add 36 litres to the tank.

CALCULATE : 6 l/ha x 6 ha =36 litres

Provided you maintain the correct pressure and speed the sprayer will deliver 100l/ha.

WATCH OUT: NOTE THE 36 LITRES THAT WAS POURED INTO THE TANK IS PART OF THE 600 LITRE USABLE VOLUME. THERE ARE INDIVIDUALS WHO THINK THAT THE 36 LITRES IS ADDED TO THE 600 LITRES. IT HAPPENS.

IMPORTANT: IS THE SPRAYER EQUIPPED WITH A PROPER WORKING PRESSURE GUAGE? "THE GUAGE DOES NOT GO OVER 2 BAR BUT THE PUMP CAN SPRAY 40 BAR. SOMETHING IS WRONG WITH THE PUMP?" SAYS THE CLIENT. 

WHEN CHECKED, THE CLIENT WAS SOLD A GUAGE DISPLAYING MEGAPASCALS.   IT HAPPENS.   SEE BLOG POST ABOUT PRESSURE IF YOU HAVE NOT READ IT ALREADY.

IMPORTANT: IS THE SPRAYER EQUIPPED WITH PROPER WORKING PRESSURE REGULATOR. " I CAN'T SET THE PRESSURE. IT WON'T GO OVER 5 BAR." SAYS THE CLIENT.

IF THE POSITIVE DISPLACEMENT PUMP'S VALVES ARE NOT SEALING PROPERLY THE PRESSURE IS LOST THROUGH THE INLET VALVES OR THE PUMP CRANK-CASING MAY HAVE CORRODED THROUGH AND PRESSURE IS LOST INTO THE SUCTION SIDE. IT HAPPENS.

And to your left the real world.

TRESPASSING - Bit o' Fun

"The Stockman" and longtime friend warned me many years ago that the "pips" are going to fly in the future.   He also told me that he'd bought three Ostriches, a male and two females. As a security measure for the farm I assumed.    At the time the investment set him back 9'000 currency coupons. You know how your brain works - I had mental pictures of Ostriches with their lionine booming voice chasing off intruders and all would be well.

It turns out that within days he'd lost a third of his investment when one female escaped, never to be seen again.  Again a mental picture of said Ostrich being dispatched and turned into a cholesterol free meal. Several meals actually.

Well it wasn't long before he informed me that couldn't walk around on the farm. The male had also kicked a dent in his new pickup.   I'm thinking -Who actually owns the farm? At one stage it even went for him while he was on the tractor. "I'm going to kill the b..........d." And he didn't say Bustard which by the way is the heaviest flying bird.   

"If you grab it by the neck, it can't do a thing." he informed me. This could be tricky considering that an adult male could weigh in at a hefty 150 kilograms and that large toe nail backed by serious thigh muscle will do some serious damage. 

The remaining female died and he finally sold the male at a net loss considering the repairs to the pickup. Anyway that's why I did the picture and it needs an appropriate caption. Here's a few: Gryp hom aan sy nek! Trespassing. Whose farm is it? Hey you dropped your hat!

CALIBRATION - LESSON 3 MATCHING FLOW TO A NOZZLE-TIP

CALIBRATION Lesson 3 - 

From lesson 2 we determined speed in m/min or km/hr.

You should be able to see that the sprayer is creating a rectangle as it travels in a straight line.

From the example the sprayer covered 120 metres every minute and each nozzle was spraying 0.5 metre wide. This created a rectangle with an area of 60 m²     

CALCULATE: 120 m x 0.5 metres = 60 m² (60 square metres) NOT 60 METRES SQUARE!

From lesson 1 the farmer wanted to apply DESTROY herbicide in 100 litres per hectare.

We know one nozzle covers 60 m² every minute so how many 60 m² blocks or unit areas makes up a hectare? 

CALCULATE: 10'000 m² divided by 60 m² or 10'000 / 60 = 166.7 blocks.

The farmer wants 100 litres to cover each hectare so what volume covers each 60m² block. Remember each block of 60 m² took 1 minute. CALCULATE: 100 litres spray mix divided by 166.7 blocks = litres for each block per minute.

OR litres / min = 100 / 166.7 = 0.6 l/min/block

TRICK QUESTION: DOES IT MATTER IF YOU USE 1 NOZZLE OR 20?

We have now determined the flow rate of a nozzle to achieve 100 l/ha travelling at 7.2 km/hr. Notice any fancy formulas? None!

The next step is to get hold of a catalogue and work through the flat fan nozzles to find the one that best matches the situation.  Take a look at the table below.

EXAMPLE: AIXR TeeJet - Air Induction Extended Flat Spray spray-tip.

TIP CODE : AIXR110015VP operating at 3 bar will do the trick. Spaced at 0.5 m or 50 cm and travelling at 7 km/hr achieves 101 litres per hectare. CLOSE ENOUGH.

CALIBRATION LESSON 2 - STILL NO FORMULAS SIMPLE ARITHMETIC

CALIBRATION - Lesson 2

SPEED - METRES PER SECOND - m/sec  AND KILOMETRES PER HOUR km/hr

PLEASE NOTE : THE AIM IS TO DETERMINE THE AREA COVERED IN A SPECIFIC TIME. AREA IS A FUNCTION OF TIME.

Previously we determined the speed of the sprayer to be 2 metres per second. Remember it travelled 100 metres in 50 seconds.

So how far will the sprayer travel in 60 seconds or 1 minute. Remember there are 60 seconds in 1 minute. At a rate of 2m/sec the sprayer travels 120 metres or 2m / sec x 60 seconds = 120 m / 60 secs or 1 minute.

Now some of you think this is ridiculous but believe me some people actually went to school and ended being dumbed down by useless teachers! Critical percepts were lost at an early age.

If 120 metres is travelled in 1 minute and we know there are 60 minutes in an hour then we can determine the metres travelled in 60 minutes or 1 hour. CALCULATE: 120 m x 60 minutes = 7'200 m / hr. Imagine you're on the sprayer. After 1 hour you will have travelled 7'200 metres. OR 7,2 kilometres.   Remember there are 1'000 metres in a kilometre.

Here's what we know.

Number of nozzle positions = 20

Nozzle spacing on boom = 0.5 metre or 50 cm. Take note : Do not get confused when using this number!   Each nozzle is covering an effective swath of 0.5 m.

Effective swath for the boom. = 20 nozzles x 0.5 m = 10 metres

Speed = 120 m / minute or 7.2 km/hr

Can you see the area covered per minute? You should get 60 m² per minute per nozzle or 1'200 m² per minute for all nozzles.

The next post looks at area and time to determine the nozzle flow rate in litres per minute.

CALIBRATION LESSON 1 - NO FORMULAS SIMPLE ARITHMETIC

CALIBRATION - To some a four letter word. LESSON 1

If you don't understand the arithmetic or the formulas you have arrived at the right place.

Here's where the proverbial light goes on.

If you need to determine the amount of spray-mix going down per treated hectare** you need a starting point. That starting point is the product label. For example let's use a herbicide. We'll call it DESTROY.

Destroy is applied at a specific rate in 100 to 300 litres spray-mix per hectare -- ha.

** A hectare is a square with sides 100 metres long. So the area is 100 x 100m = 10'000 m² (ten thousand square metres) Be very careful when dealing with row crops and calculating litres per field hectare.  If you are only treating 5'000 m² for every field hectare then a treated hectare will obviously mean every 2 field hectares.

IN PRACTICE IT IS ASSUMED YOU HAVE THE CORRECT NOZZLE TIPS FITTED TO THE SPRAYER.   THE FARMER OR CHEMICAL REP THEN HAULS OUT A FORMULA AND DRIVING OR WALKING AT A SPECIFIC SPEED CALCULATES THE SPRAY-VOLUME PER HECTARE.   IF YOUR HAPPY WITH FORMULAS, GOOD BUT THIS BLOG POST IS ABOUT UNDERSTANDING WHAT IS ACTUALLY HAPPENING.

This image courtesy of R Steenkamp

To be efficient you want to spray the least amount of spray-mix which in this case is 100 l/ha. (litres for each hectare)     Transporting water costs money so cutting down on refill times is crucial.  It is vital that you know how many actual practical working minutes you have in a day.   I have demonstrated in field that is possible to spray 30 l/ha using a boom-sprayer and therefore possible to spray 20 hectares with a 600 litre tank.   But there may  not be enough spraying time in a day to empty the tank. So, be careful.  Another important point is  as spray-volumes go down management goes up.   You can't afford to make errors with high concentrates!

You know what volume you need to put down but you also need to know the speed you are travelling at. When determining speed make sure you are doing it in the situation you will be spraying.   WHY?    BECAUSE WE ARE TRYING TO DETERMINE THE FLOW RATE OF THE NOZZLE WE NEED TO MATCH THE SPRAY VOLUME YOU WANT!!   READ THAT AGAIN.

SPEED AND AREA

We'll assume that you have a 100 m tape measure and a stop watch. Mark off accurately 100 metres in field. You can also use 50 metres.   Determine the time taken to travel the distance. Do it both ways and if needs be do it in a different area in the field to be treated.

You end up with seconds to cover the distance. EXAMPLE: It takes 50 seconds to cover 100 metres. You also know the number of nozzle positions and their spacing on the boom.

TIP: THE EFFECTIVE SWATH (HOW WIDE THE RIG SPRAYS) IS SIMPLY THE NUMBER OF POSITIONS MULTIPLIED BY THE SPACING.   EXAMPLE : 20 NOZZLE POSITIONS AND SPACING IS 50 CENTIMETRES OR 0.5 METRE. THE EFFECTIVE SWATH IS 0.5 m X 20 nozzle positions =10 METRES.

Next posting we determine speed in kilometres per hour and the area covered in a specific time.

TECHNICAL - SMALL FILTERS

SMALLER FILTERS (AKA    STRAINERS )

Here are the small filters that fit into the standard bodies supplied by most spray equipment manufacturers.

MATERIALS AVAILABLE              Polymer, brass or NYLON with stainless steel mesh elements.

MESH SIZES

The mesh size refers to the number of blocks per inch. For example the 50 mesh element has 50 blocks per inch. The higher the number the finer the element. As you can see the red filter is 50 mesh and the green filter has the 100 mesh element.

 This is the 50 mesh brass filter with stainless steel mesh.  These are also available in non-drip form.

In the case of the slotted filters the red one would be the 50 mesh equivalent and the yellow slotted filter as illustrated below is the equivalent of a 25 mesh. Used primarily with disc and core nozzles.

Please note mesh size does not refer to microns.

IMPORTANT POINTS

Match the filter MESH SIZE to suit the nozzle-tip. THESE ARE SPECIFIED IN THE TEEJET CATALOGUE. The filter mesh size is specified in parenthesis below each nozzle code.  Usually in the 1st column.   DO NOT USE FILTERS FINER THAN SPECIFIED AS THESE WILL QUICKLY BLOCK RESULTING IN REDUCED FLOW AND INCORRRECT APPLICATION.

NOTE, IF FILTERS ARE NOT CLEANED REGULARLY THEY WILL EVENTUALLY BUILD UP DEPOSITS AND BLOCK!!

GENERAL EQUIPMENT - NOZZLES DUST SUPPRESSION

DUST SUPPRESSION ON ROADS USING THE WIDE ANGLE LARGE CAPACITY FLOODJET  -  1 K 450

Vehicles on farm roads create huge amounts of dust.  It settles on the crops.  Farmers are not happy.  Putting up signs showing speed limits and or warnings about the effects of dust on the crops are, like most laws, merely ignored.   So the next best thing is to tackle the problem with water and keeping the roads moist during dry periods. Here's a setup showing four huge Floodjets used by the road construcion companies. 

The farmer may need only one.  The problem! Tank capacity.  Each of these nozzles guzzles up 290 litres per minute at 2 bar.   Mounted correctly and fed with right pump it will achieve a swath of about 6 metres. 

Here's a pic of  the B1K450.  1 inch BSPT inlet and nominal orifice diameter of 18mm.

SPRAYGUNS - Orchard gun the AA2A Gunjet

Spraying tree crops, livestock and power washing

AA2A-30  This is the aluminium version.  

Pressures from 2 to 55 bar. Sprays from a solid stream to a hollow cone pattern.

To operate the GunJet rotate handle through 360° from shutoff to maximum flow. Actually it's less than 360 degrees.  

Here's a picture showing the cap and tip assembly with a selection of  hardened stainless steel tip inserts.  By the way all heat treatable stainless steel rusts. 

The number 30 hardened stainless steel nozzle-tip is the most popular and it can be simply replaced with others in the series. The number 30 when set to the wide angle cone delivers 3 litres per minute at 7 bar and 8.5 at 55 bar.

The number 20 is the smallest and when set to the wide angle cone it delivers 2 litres per minute at 7 bar up to 5.8 litres per minute at 55 bar.

Length 380 mm and weighs a mere half a kilo. The inlet is a common ¾ inch garden hose thread.

PRESSURE RELIEF AND THROTTLING VALVES

Piston Type

23120 available with 1/2” and 3/4” inlet and bypass. Also a 1/4” port for a pressure guage. Port plug also included. Pressure rating either up to 4 bar -60 psi or 10 bar - 150 psi.

NOTE:       23120 A fitted with 316 stainless steel spring and Viton o-ring for better chemical resistance.

The male thread screws into a tee-piece on the pressure side of the system. The bypass (female outlet) returns excess fluid back to the supply tank.

Pressure is adjusted by turning the top knob. The locknut holds the knob and maintains the selected pressure.

I have seen cases where the regulator is fitted in-line.  Not a good idea! The male threaded inlet as in image is fitted into the supply line and the female outlet  is fitted directly to the delivery side.  That's when you get a call telling you that,  "I can't adjust the pressure."

TECHNICAL - PRESSURE – KILOPASCALS, MEGAPASCALS, BAR, PSI

Take a banknote and place it on a table.  The downward pressure exerted by this note is supposed to be about one Pascal.  Pressure is the force per unit area.   I’ll get back to Pascals in a moment but first…….
In the old days when most countries were using imperial units, the pressure at average sea level or standard pressure was equivalent to 14.7 pounds per square inch.  So, while you’re lazing about on a beach there is an atmospheric pressure of 14.7 pounds being exerted on every square inch of your body. Think in terms of air molecules bouncing around and knocking onto you.  While you’re at it think what happens to pressure the higher up we go.  Fewer molecules bumping onto you.  
Today most of us that can afford motorised transport are more familiar with the term bar. No! Not to confused with the publican where you pop in for a drink or two.    At a garage we either have to check  tyre pressures ourselves or ask an attendant to check it.  You may hear,  “Two point three bar all round”  or “Two  up front and two point four at the rear.”  Of course, if you had ask the motorist what bar means most wouldn’t have a clue. 
1 Bar = 0.98692 of a standard atmosphere or 14.504 p.s.i. (pounds per square inch)    How do we get from bar to Pascals?   Getting back to that banknote we can see that 1’000 of these notes makes up a kiloPascal  = 1kPa.  The important thing to remember is that 100 kiloPascals or 100 kPa’s = 1bar. Sounds like 100’000 banknotes to me.
GUAGE PRESSURE
Guage pressure is the pressure relative to the local atmospheric pressure.
Take a closer look at these guages.  The one on the right indicates pressures up to 600 kPa or 6 bar.  The bottom guage will measure relative pressures up to 4000 kPa or 40 bar while the top guage measures pressures in MPa or Megapascals.
Megapascals????   Just remember that 1MpA =10 bar.  So this particular guage measures relative pressures up to 600 bar or 60’000 kPa.  That’s alot of banknotes!
So what are the bubbles for?  These guages are all filled with glycerine.  The purpose is to merely stop the indicating needle from vibrating so that is easier to see the indicated pressure.  Think in terms of pumps with pistons whizzing – valves bouncing around and you will understand why the needle will not stay still. 
Before moving on to an example take a look at this image. The guage on the top right has a back entry.  As a matter of interest the “rubber”  plug is there to equalise the pressure in the guage with atmospheric pressure. 

This guage shows a bottom entry.  Let’s get back to the garage example. So now you can understand that there is already external atmospheric pressure being exerted on the vehicle’s tyre so when filling the tyre to 2.3 bar or 230 kPa the guage is indicating relative pressure.    At sea level you would have to add another 100kPa or 1 bar to get  the absolute or “true pressure”.   In our example the absolute pressure in the tyre will be 3.3 bar or 330 kPa.
If you have been following these posts then you now have most of the essential concepts to move onto more interesting aspects of product application.
