1.Identifying problems related to dome dryer installed in Sahyadri school

2.Maintenance of dome dryer

I and Shubham Shembde Sir visited Sahyadri school on 8th June 2019 to Identify problems related to dome dryer installed there and to do maintenance of it. We identified problems they are facing and took their feedback about dome dryer working.

After visiting the school in the morning, we asked some questions and we understood some issues are as follows,

  1. Moisture content increases at night as humidity increases
  2. Rehydration happen due to fog
  3. Structural Integrity was poor
  4. Wires were bent during shifting plates.

After identifying issues, we asked them about what type of vegetable and fruits they dried in Dome dryer so, they dried 7 substrates,

  1. Chikoo                     4. Banana                  7. Cluster bean
  2. Okra                      5. Tomato
  3. Mango                     6. Onion
Dried banana and mango sample

According to them, Chikoo took 8 days to dehydrate. They dried 6 kg Chikoo in dome dryer and they got 600 gm dehydrated Chikoo. Their other observation was the taste and color of dried Chikoo is not changes. The food value of dehydrated Chikoo remains the same. After drying Chikoo they send dried samples to sale.

Okra took 4 to 5 days to dry. Mango slices will dry in 8 days and because of sucrose, dehydrated mango slices didn’t get hard after drying. The banana will dry in 4 days and they dried 5kg banana slices and they got 500 gm dehydrated banana. One thing that is common in all these substrate dehydrations is the taste and color didn’t change that much.

Shubham Sir and I tasted samples and they were excellent in taste. Rajashri aunty works on dome dryer there and their feedback encouraged us to make more than enough for dome dryer, she said,

  1. Dome dryer is easy to operate.
  2. Substrate dries easily and in possible minimum time.
  3. Taste of dehydrated product is good.
  4. The functionality of the dryer is good.

  2. Some wires were not in proper position because of inappropriate handling Shubham sir and I made that proper.
  3. We did the insulation of the trays.
  4. There was a problem in handling trays and we resolved it. Shubham sir taught them how to operate a dome dryer properly one more time.
