Trials on prototype

Firstly, I have trial taken on mataki and following reading were taken-

Amount of mataki – 100gm

Following details give the ON/ OFF timing –

ON (time)	OFF (time)
7.00	7.02
9.00	9.02
10.00	10.03
11.00	11.03
12.00	12.03
13.00	13.03
14.00	14.03
15.00	15.03
16.00	16.03
17.00	17.03
18.00	18.03
19.00	19.02
21.00	21.02
00.00	00.02
3.00	3.02
6.00	6.02

After sprouting (26 hrs) weight of mataki – 324gm

Conclusion – Mataki sprout came after 26 hrs which was less than previous trials. But the requirement for sprout is less than 17 hrs hence more trials will be taken.

Trial 2^nd

I have taken second trial on mataki –

Amount of mataki – 100gm

Following details give the ON/OFF timing

ON	OFF
7.00	7.02
9.00	9.02
10.00	10.03
11.00	11.03
12.00	12.03
13.00	13.03
14.00	14.03
15.00	15.03
16.00	16.03
17.00	17.03
18.00	18.03
19.00	19.02
21.00	21.02
00.00	00.02
3.00	3.02
6.00	6.02

Initial weight of mataki – 100gm

Final weight of mataki after sprouting (20 hrs) – 336gm

Conclusion – In this trial mataki sprouted after 20 hrs. Therefore in this second trial mataki get less time than previous trial.

Trail on Sprinkler

Today, I took out the trail of the sprinkler to spread the water uniformly on to the mataki. It resulted out with that the water spread out through the sprinkler was not spread uniformly on to the surface of the mataki.

Three sprinkler attached on the one lateral.

So, for uniform spray, I took three sprinkler for one tray, and that is for six tray 18 sprinkler were taken. Then after, by setting up all the sprinkler the trail was carried out. During this trail, I took about 100 gm of mataki. After the trail I got to the conclusion that there was uniform spraying of water in the last tray (bottom tray).As I went to the result of another above tray, the water was not spray uniformly on the mataki. Now this result made and conclusion that as the pump head rises at the top trays the pressure decreases and this conclude to an nonuniform spraying of water of the top. There is differing in pressure ranges at top and the bottom of the tray.

So, I got to an conclusion that referring Pascal’s law the sprinkler should be place at an equal distant to pump.

Trail on Door

It was neither possible to attach the foam door with rivet nor with glue gun.

Therefore I decided that plastic cover used for the door.

Calculation of the discharge of the pump

Above this calculation,I calculate the pressure of the motor and discharge of the one sprinkler. But above calculation might be wrong.

Above this calculation, I calculate the pump WHP. But above calculation might be wrong therefore I decided to another method.

Above this calculation, I calculate the theotical discharge and actual discharge.

In this trail I observed how much water evaporate in 1 hr.

Trail on sprinkler –

Water required for Mataki is 50 ml but in this trail discharge of the 4 sprinkler is 100 ml. So sprinkler system will be change. Also, pump get the less discharge therefore we need change the pump.

Pump specifications –

Voltage – 165 – 220 V/50Hz. Power – 40 W. H-Max – 2.8 Mtr. Output – 3000 LPH.

After pump selection two sprinkler attached on the lateral.

Conclusion – This system works well for peas

Overall conclusion from above all trials;

The prototype of sprouter worked well without for all except chhole where not proper sprouting observed and also the foul smell and stickiness was observed.
This system works well for large quantity (about 1.5kg) of all seed.

Trial 6

1 kg of finger millet was taken and it was kept inside the structure from 11.00 pm to 7.00 pm (next day) without soaking.
The inside temperature of structure was 30˚C.
10 sec/ hr water sprayed on the finger millet for first 10 hrs. by setting of the timer.

Result –

Final weight of finger millet after sprouting is 1710 gram.
Time required for sprouting of finger millet is 32 hr.

Conclusion –

In above trial it was seen that finger millet had no foul smell and they no sticky form.
This system works well for finger millet.
