1 M/S Jaimin Engineering

Pvt Ltd.

I) Provide soil test report of location?

The soil testing report would be sent to all participants by Monday or Tuesday i.e. 12th or 13 instant.

ii) Which variety of fresh onion going to be stored?

Varieties to be stored are: a. Crystal b. Talaja white local c. Agrifound white

iii) What will be the farm condition of onion that are going to be stored?

For fresh onions: a. The neck tissue is tight b. Outer scales (2 nos.) are dried until they rustle. c..Water moisture content loss should be between 3 to 5 %

iv) What will be the packing details of onion flakes ?

1.0 Dehydrated onions shall be stored in paper cartons / Jute bags etc 2.0 Fresh onions shall be stored in cartons or boxes

2 M/S Mech-Air Industries, Vadodara

i) Ref: In Section-5 D & Section -6 pg.28-59 What is meant by the best

1) Since the ventilation system for fresh onions has not yet been commercially established in India

124

manufacturer is mandatory, as you have not given any technical details regarding air dehumidification and ventilation per 6.2D Pg.59.

and hence we invited latest & proven technology for the same. Involving technology suppliers from abroad.

ii) No additional cooling load is mentioned for Dehumidification. You have provided only functional requirements and not technical details. Due to which we are confused. While maintaining dehumidified conditions, additional cooling load will be added. Have you calculated in your design?

The item is MANDATORY since without perfect ventilation, fresh onions cannot be stored long in cold stores. The additional cooling load has been taken care of for dehumidification.

iii) As per Annexure 1 & 2 on pg.50 and Section 5 B 1. What is the exact storage temperature for fresh onion? 2. What is the daily incoming product load of fresh onion?

1. The exact temp. of fresh onion will vary as per different varieties from minus 3 deg. C to + 2 deg. C( Average ) 2. Though this parameter is required only to calculate basically refrigeration load required. However, the average incoming product qty is 22 MT and 15 MT for dehydrated & fresh respectively per day.

125

3. What is the respiration load at that storage temperature? 4. What is the total storage life of fresh onion during storage in months /days? 5. What is the exact relative humidity required for fresh onion storage? Give RH with tolerance.

3. ------------- as per the data published by ASHRAE USA. 4. 6 – 8 months 5. 65 – 75 % which is already specified in tender on page no. 47.

Queries by Participants Clarifications

For Dehydrated Onion Storage 1. What is the storage life? 2. What is the exact storage temperature for DH onion? 3. What is the exact RH required? 4. What is the exact storage cost of fresh onion and DH onion per kg per month considering all power consumption?

1. 6 – 12 months 2.0 As informed above it varies from minus 3 to 2 deg.C 3. 65 – 75 % as indicated above 4. There is no need at all to have the information on storage cost since it is an operational requirement.

126

3 Point 6.2 B.A) Condensing unit

Why only imported Copeland/Zanoti/ Emerson make condensing unit? Indian make are not competent with using above compressors?

We have observed & experienced that imported units or the ones manufactured with collaboration with international reputed brand, are high in efficiency, precision and more reliable.

4 Point 6.2 A.B.B) – Air cooled condenser Cu tube of 13mm Dia. With 6-8 FPI

Normally condenser for 4 TR capacity using R134a system, is from 3/8” O.D. with 12-13 FPI. Why you have 13mm Dia. With 6-8 FPI. Pls. clarify.

The design has been suggested by our consultant. The same design has been used in our earlier projects and all are working satisfactorily. The cost difference for these units is highly insignificant.

5 Point 6.2.B.B) – Air handling units & Cooling coil

1. Why Star cooler / Guntner / Kueba /Helpman make only? No Indian make is competent enough? 2. As design room temp is 22-24 Deg.C, then why coil should be fabricated from 5/8” OD with 8 FPI. Please clarify. 3. Normally in air conditioning it is used 3/8” OD with 8-10 FPI, why to increase the cost?

For your information star cooler is an Indian manufacturer with collaboration from U.K. located at Jalgoan. Their products have been already tested earlier and found to be very efficient and power saver. Also if the imported units with proven records are available at competitive cost then why we should not go for that?

127

6 Working of the system throughout the year

Now we understand that the storage life of fresh onion is not more than 4-6 months whereas the Dehydrated Onion can be stored for 1 year. So why are using the common refrigeration system for storing both the products? Ultimately the total power consumption burden comes on the customer/farmers. Are you happy with this? Is this the goal of the Gujarat Agro for the farmers/customers, who is putting the value added commodity for storage?

The common ammonia refrigeration system is an international standard and all the chambers can be independently operated for different temperatures and humidity. Our consultant has designed this system to get operational saving. hence, there is no question of burden on farmers by GAIC.
