Our pasteurization tanks are made in AISI 304 or 316 stainless steel, are completely insulated to the outside and are heated by steam, electricity or gas.
The operator can set the cycle of pasteurization and cooling more useful to the production because each unit has its control board which permits to set time and temperature of pasteurization and cooling. The operation cycle starts with closing of the cover by means of a pneumatic piston (available only for the biggest model, while for the smaller one the closing is manual).
Water filled in the pasteurizer tank automatically, is heated up at the set temperature. Pasteurization temperature is kept for the required time and then starts the cooling cycle, with adding of fresh water from a dedicate valve.
An alarm signal warns the operator when the cycle is finished. There are several models of batch pasteurization units: the smallest is heated by electricity (9 KW installed), by gas or steam.
For the biggest model the heating is usually made by steam (in some case even by gas). The working capacity expressed in number of vessels per cycle is from 120 jars for the smallest unit to about 1000 for the biggest unit.
The total duration of the cycle change from 60 to 120 minutes according to the size of the vessels and the kind of product. The same unit – with some minor modifications – can be also used as blancher for fruits and vegetables.
