Products that can be processed in our rotary coil defrosters

ADVANTAGES AND SPECIFIC FEATURES

AUTOMATION
In the most advanced versions, it is controlled by a PLC with touch screen operator panel and is completely automatic.

The operating parameters such as speed and temperatures are fully programmable.

VERSATILITY
Can be used with any vegetable or fruit type.

RELIABILITY
Designed for durability and low maintenance 

PROCESS CONTROL
The different heating systems can be activated independently and simultaneously. Together with the variable rotation speed of the trough, the heat treatment is controlled promptly and in a modular manner.

SAFETY

All our defrosters are equipped with all the safety systems necessary to comply with the requirements required by European directives and comply with the CE marking.

PED-certified pressure equipment

ROTARY COIL DEFROSTERS-PREHEATERS

Machine with trough structure, heated by steam, or hot water if required, through the internal surface of the structure equipped with cavities, the hollow rotating shaft and the coil connected to it.

Optionally the following heating systems can be used, even partially associating them:

  • Indirect heating through the steam jacket and/or shaft with rotary coil.
  • Direct steam injection heating through the steam injectors.
  • Mixed heating.
SCONGELATORE-A-SERPENTINO-ROTANTE-PART

The product enters the machine from one end and exits continuously from the opposite side through an opening on the bottom and connected to a volumetric extraction pump.

The pump speed is controlled by the level regulator.

The machine is composed of two "U" shaped metal sheets, one inside the other, forming the supporting body and the cavity, inside which the heating fluid circulates.

The two ends are closed by two openable heads, specially shaped to form the support of the rotating axis.

It has a series of watertight lids that can be opened on the hinge and fixed by means of snap hooks.

A series of special steam injectors are placed on the machine bottom generator.
Each injector is equipped with a shut-off valve.

A rotating shaft, consisting of a tube through which steam circulates, on which a helical spiral tube is mounted for heating and feeding the product.
