FOOMA Japan 2013, International Food Machinery & Technology Exhibition, brought together more than 94,000 attendees over the course of four days. 725 companies presented their technologies related to food manufacturing and processing. attended the event to meet suppliers using natural refrigerants. Ammonia refrigeration was prepresented mainly by leading Japanese manufacturer Mayekawa displaying among others the new design concept of a tunnel type freezer named CooLDo. +PHOTOS<

Organised by The Japan Food Machinery Manufacturers’ Association, FOOMA Japan 2013 attracted 725 exhibitors and 94,087 visitors between 11 and 14 June. The FOOMA trade show brought together major companies and experts within the food machinery world to present and discover latest industry developments. reports on products on display at booths of Mayekawa, Kobe Steel, JBT FoodTech and Hisaka Works.

NewTon F refrigeration system for food processing with 20% gains over R22 system

On display at Mayekawa booth was an ammonia compressor unit of NewTon F-800 – refrigeration system developed especially for freezers in food processing plant. The NewTon F-800 features a two-stage semi-hermetic screw compressor and has a cooling capacity of 170kW (other available models with cooling capacity of 70kW and 140kW). All NewTon systems use ammonia as primary refrigerant and CO2 as a secondary refrigerant, the ammonia refrigerant is therefore kept safely in the machine room and leakage risk of the ammonia refrigerant is limited to minimum. NewTon F series supplies CO2 to freezers at temperature of -42°C. According to product brochure NewTon F series is 20% more energy efficient that refrigeration system using R22 refrigerant. According to Mayekawa, NewTon is increasingly popular all natural solution in Japan due to high energy efficiency and reliability of the well proven technology.

CooLDo – sign of a modern design features coming to HVAC&R industry

Attracting the eyes of all show attendees was the world’s premiere of a re-designed Thermo Jack Freezer called CooLDo exhibited together with NewTon F’s compressor at Mayekawa booth. The prototype of this new model of a tunnel type freezer for continuous rapid freezing was exhibited in order to receive the first feedback from the food industry. CooLDo is a modern concept with design features more common in spaceship or highspeed train than HVAC&R industry. It will be interesting to see if the model entering the market eventually will keep the progressive design features.

Spiral freezers, heat exchangers and complete systems for R717 refrigerant

Another player in the ammonia refrigeration on the Japanese market, Kobe Steel, provided information about its new product lineup of semi-hermetic single stage and 2-stage ammonia inverter screw compressors. Although a R404A unit of identical design was on display, marketing materials and product brochures provided information about the unit using ammonia refrigerant. The iZ SN (single stage) unit is available with motors of nominal output 37 – 125kW for temperatures from 0°C to -30°C and iZ N (2-stage) compressor systems of nominal output 24 – 125kW for temperatures from -30°C to -50°C.

JBT FoodTech, provider of freezer solutions for the freezing and chilling of various food product, exhibited the GYRoCOMPACT spiral freezer equipped with ammonia-optimised evaporator system with 2 fans (49kW) or 3 fans (67kW). Japanese manufacturer of plate heat exchangers, Hisaka Works, had on display large scale plate heat exchangers and also small scale titanium tube heat exchangers. Although in food related industry the heat transfer medium is usually water, both exhibited exchangers work well with ammonia refrigerant.
