Name of the Project: ‐ Cold storage for PEPSICO Process Potato 15000MT
Year of Commissioning: ‐ 2021
This is a Green Field project and we have installed, tested and commissioned this 15000 MT cold storage for Process variety of potato for PepsiCo. This plant is designed to maintain desired storage parameters (Temp, Humidity, Co2) with advanced ventilation system. This is an ammonia based glycol cooling coils refrigeration plant with PLC operation. Glycol being cooled in Plate type heat exchanger by ammonia and further circulated in Pumps. So the charge of ammonia is reduced and limited to machine room area about 1700kg of ammonia. This is a green refrigerant. We have used VFD in Pumps and compressors to optimize the cost of operation. Each chamber is being provided with individual glycol pumps with VFD to maintain the chamber temperature close to set point ( +/‐ 0.5deg C) by speed control of pump. All piping is SS to avoid corrosion due to chemical reaction. We have achieved potato loading capacity inside chamber on per day basis up to 1000MT with loading conveyors & machineries fully design & built by NSSPL. Plant is fully PLC operated.
This is basically storage of process variety of potatoes in BULK and wooden BOX. We have installed potato handling machinery from receiving/unloading from truck to loading inside chamber with grading facility. The line capacity of material loading is 80,000kg per hr basis. The total storage is 15000MT in 12 nos of chambers.
