Sprouter (Household)

Introduction:

Sprouter is used to sprouting of pulses.

Sprouting is the natural germination process which improves the digestive process.

The health benefits of sprouts make up quite an impressive list, and they include the ability to improve the digestive process, boost the metabolism, increase enzymatic activity throughout the body, prevent anemia, aid in weight loss, lower cholesterol, reduce blood pressure, prevent neural tube defects in infants, boost skin health, improve vision, support the immune system, and increase usable energy reserves.

There are many types of common bean sprouts:

• Mung bean sprout is made from the greenish-capped mung beans
• Soybean sprout is made from the yellow, large-grained soybean

• Pulses (legumes; pea family):
  • pea, chickpea, mung bean and soybean (bean sprouts).
• Cereals:
  • oat, wheat, maize (corn), rice.
• Oilseeds:
  • sunflower, linseed, and peanut.

Objective:

1. To optimize the various conditions for sprouting such as temperature, humidity.
2. To work on the sprouting of pulses.
3. To design small household sprouter.

Prototype first:Date:4/6/2019

• First, take a trial on big sprouter.
• The trial took on the peas.
• This system works well for peas.

The trail for small sprouter:

Prototype second: Date: 5/6/2019

Took a wooden box which is insulated inside by thermo-col.

fixed small piece of sponge in it.Also, dry bulb and wet bulb thermometer fixed in that box.

First 100 ml water is added in the sponge.

And checked the relative humidity in the box after the interval of one hr. from the below reading.

Sr.No.	Time	Dry bulb	Wet bulb	Relative Humidity (%)
1	10:27am	32	29	79.26
2	11:27am	29.5	26	74.84
3	12:27pm	29	26	78.02
4	1:27pm	32	29	79.26
5	2:27pm	32	29.5	82.55
6	3:27pm	32	30	85.95
7	4:27pm	34	32	86.41
8	5:27pm	35	31	74.26

From these reading it was seen that the humidity is not properly maintained due to improper insulation inside the box also the outside humidity is not recorded by me.

Again trial for relative humidity:

Prototype third :Date:6/6/2019

New insulation of thermo-col is provided in the box.

In these experiment I will took 50 ml water in the given sponge, and the reading are as follow,

Sr.No.	Time	Dry bulb	Wet bulb	Relative Humidity (In box)	Relative Humidity (Atmosphere)
1	10:45am	32.5	28	69	69
2	11:45am	31	28	78.86	63
3	12:45pm	31.5	28	75.80	59
4	1:45pm	32	29	79.26	59
5	2:45pm	32	29.5	82.55	58
6	3:45pm	31.5	28	75.85	61
7	4:45pm	28	32	72.85	62

From these also seen that relative humidity averagely maintained. But here also the humidity and temperature is disturbed due to uniform opening of the box while getting reading.

Prototype fourth:Date:7/6/2019

Here also 50 ml water is added in the sponge.

Sr. No.	Time	Outside temperature	Outside humidity	Dry bulb	Wet bulb	Humidity
1	12:19	36	59	–	–	–
2	1:19	35	59	33	29.5	76.46
3	2:19	35	64	32	29.7	83.86
4	3:19	36	65	33.5	30	76.67
5	4:19	36	65	34	31	79.99

here the average difference between outside and inside humidity is 20%

Prototype fifth:Date:8/6/2019

Here also 50 ml water was added in the sponge.

Sr. No.	Time	Outside temp.	Outside humidity	Dry bulb	Wet bulb	Humidity
1	12:50	34	60	–	–	–
2	1:50	34	59	30.5	28	82.05
3	2:50	34	62	31	27.5	75.57
4	3:50	35	60	31.5	27.5	72.60
5	4:50	34	60	31	27	72.34

here average difference was 15%

Prototype sixth:Date:10/6/2019

Sr. No	Time	Outside temperature	Outside humidity	Dry bulb	Wet bulb	Humidity
1	12:22	33	69	–	–	–
2	1:22	34	62	29	26	78.02
3	2:22	34	62	31	28	78.86
4	3:22	34	64	30.5	28	82.05
5	4:22	29	68	29	26	78.02
6	5:22	29	65	28.5	26.5	84.92

here average difference was 20%.

Trial first for pulses:Date:12/6/2019

• In first trail 50-gram, matki and 50-gram cowpeas are taken.
• These are soaked in water for 8 hours.
• Then put in the box for sprouting for 12 hours.
• In this box the sponge with 50 ml. water is fixed.
• Weight of box =7.09 gram
• Weight of the box with water=50.64 gram

Result:

	Inside dry bulb	Inside wet bulb	Inside humidity	Outside temperature	Outside humidity
Initial	29	26	78.02	24	83.15
Final	28	26	84.76	29	77.08

• The final weight of sponge=47.07 gram
• In the trial, it was seen that cowpeas had the fungus, foul smell and it becomes sticky.
• And the matki haad no smell and having good sprouts.

Trial Second:Date:13/6/2019

• In second trail chickpeas and cowpeas are taken and soaked for 8 hours.
• And the sponge is soaked with 30 ml water.
• These are put in the box for 22 hours.
• Weight of sponge =3.97 gram
• Weight of the sponge with water=25.85gram

Result:

Final weight of sponge=22.05

	Inside dry bulb	Inside wet bulb	Inside humidity	Outside temperature	Outside humidity
 Initial	28	24	70.62	24	–
Middle	28	26	84.76	29.5	–
Final	29	27.5	88.70	31.5	62.27

In these, it will be seen that the chickpeas having sprouts with no foul smell and stickiness but the cowpeas getting fungus and sticky again.

Trial third: Date:14/6/2019

These trial was taken for cow peas.

In this trial, 30 ml of water was added in the sponge in the box and soaking time is reduced to 5 hours and sprouting time was 12 hours.

Result:

	Dry bulb	Wet bulb	Inside Humidity in %	Outside temp.	Outside humidity
Initial	29	25.5	74.59	29	70.31
Final	28.9	27.5	89.41	30	87.67

Again the cow peas getting fungus and foul smell.

Trial fourth: Date:15/6/2019

Thus trial taken for chhole and mug.

30 ml water is added to the sponge and the soaking time of chhole and mug was 12 hours and sprouting time was 12 hours.

Result:

	Humidity
Initial	80.93
Final	87.96

Chhole had get foul smell and also get sticky. Mug was get sprouted with no smell.

Trial fifth: Date:17/6/2019

These trial was taken for cow peas.

In this trial, 20 ml of water was added in the sponge in the box and soaking time is reduced to 3 hours and sprouting time was 12 hours.

Here the water quantity is decreases due to less evaporation.

Result:

Both methods was failed for the cow peas.

cowpeas in box getting fungus and sticky and also foul smell, and this causes similar in the traditional method.

	Humidity	Temperature
Initial	77.56	29
Final	81.87	26

Trial sixth: Date:19/6/2019

These trial was taken for Horse gram.

There were 50 gram of horse gram are taken and soaked for 10 hours.

In this trial, 20 ml of water was added in the sponge in the box and sprouting time was 12 hours.

Here,

Weight of sponge =4.80 gram

Weight of the sponge with water=26.56 gram

Final weight of the sponge= 11.35 gram

Result:

	Dry bulb	Wet bub	Inside  humidity	Outside temp.	Outside humidity
Initial	28	24	70.20	27	76.57
Final	29	26	78.02	33	69.9

There was no foul smell for the horse gram.

It getting good sprouts.

Date:21/06/2019:

I made a tray for big sprouter on this day. And the mesh was used for that.

In the big spruoter kept a batch of horse gram.

There were 1.5 kg of horse gram was taken.

And got a good result.

Date : 24/06/2019

On this day new box for sprouter was taken.

This box insulated by the thermocol.
