HTST – Pasteurizers HTST

H.T.S.T means high temperature short time. Many products such as milk, juice, wine and other liquid food can be pasteurized.

Pasteurization is a process of reduction of the bacterial load through a treatment at high temperatures. HTST pasteurization uses high temperature for a short period of time. The pasteurization process requires at least 3 phases: sanitation, production and washing.

1) The sanification is the preparation of the machinery and of the interconnected pipes by water which is superheated at sterilization temperature to obtain a sterilized environment.

2) The production of the pasteurized product required 3 step: heating up to the pasteurization temperature, holding time and cooling. FDB ITALIA provides a technology aimed to save thermal energy by means of recovery of the calories of the product to be pasteurized and water at different temperatures.

3) The washing provides a high flow of water mixed with sodium hydroxide around the machine to remove all the waste that may remain inside.
These 3 phases are continuous and can be managed locally or remotely.

The HTST pasteurizer is equipped with several safety control to avoid possible contamination and ensure the pasteurization of product.
The machine is preassembled on stainless steel platform and it is composed by , plate heat exchange, 3 pump, holding tube, a little process tank, command board and several valve and sensor.

FLOW RATE AND POWER OF PASTEURIZERS
Useful general details are reported on the flow rate and power consumed (or installed) by the machine. The flow rate depends on the viscosity of the product. The highest flow rate value for each model is obtained with milk or water.

AUTOMATION
All pasteurisers can be equipped with different levels of automation. Automation allows you to avoid wasting energy and save money. It can coordinate different phases with maximum efficiency and control the valves at the right time to save product. It allows to connect and synchronize different machines entering or exiting the pasteurizer. Several recipes can be set and stored on the control panel. Automation is offered in 4 different levels: basic, light automatic, automatic and full automatic. The features are summarized in the following table:
