TWIN DOUBLE DRUM SPIRAL FREEZER

double-drum-spiral-freezer

Advanced Twin Double Drum Spiral Freezer 

The new spiral freezers feature many hygienic features as standard, for example, a fully welded floor and open steel sections used for the framework. In addition, there are also options such as a fully welded and easily cleaned enclosure and advanced cleaning systems. The Advanced Twin Double Drum Spiral Freezer is designed to enable an easy installation on production floors where space is restricted. The Advanced Twin Double Drum Spiral Freezer is available as either a conventional low tension spiral or, as an option with DDS (direct drive system) which can offer reduced belt tensions and smoother running. The construction of the drum is designed for fast setup and efficient local installation. This flexibility continues throughout various single- and dual-drum designs and offers several possibilities for infeed and outfeed conveyors. As a result, it is easily possible to integrate an Advanced Twin Double Drum Spiral Freezer system in existing production lines. The new freezers and coolers not only combine the positive characteristics of other series in one modular concept: they also offer the benefits of numerous innovations – for example, optimized operator-friendly controls, and safety functions specially designed for operational conditions in Europe.
Advantages(comparing with tunnel freezer with same output capacity):
  • Saving energy consumption;
  • Saving flour occupying;
  • Retention time is much flexible; the adjusted range is larger.


DRUM SPIRAL FREEZER

Ideal solution for packed or large size products

WORKING PRINCIPLE

The Product is fed directly onto the freezer conveyor belt and transported into the freezing zone.A  cConveyor belt on tier carriers travels up around rotating drum that driven by central capstan drive. The cold air is circulated continuously through product surfaces and evaporator coil by axial fans. Cold air will rapidly freeze the product during conveyor belt movement from infeed to outfeed.

A unique built in full Stainless Steel construction, Advanced Twin Double Drum Spiral Freezer has set new standards in spiral freezer design and ergonomics, allowing for operational efficiency, ultimate durability, low maintenance, easy cleaning and great flexibility.

Drum spiral freezer of hygiene design features a unique pattern of air circulation, ensures even and quick freezing without excessive airspeeds that might damage delicate products.

Each freezer can be customized to meet individual customer requirements.

MAIN STRUCTURE TWIN DOUBLE SPIRAL FREEZER

1. Stainless steel conveyor belt:
The conveyor belt is made of food grade stainless steel. The surface of belt is flat and neat. There are baffle edges on both sides of belt, which can prevent the products from dropping down.
2.Insulation panels:
PUF sandwich panels, 150mm thick with 42kg/m3 density, laminated both sides by stainless steel sheet.
3.Door:
Equipped with double seals and frame heating system
4.Inner structure:
The drum is designed in squirrel cage structure, and the components on which touching with conveyor belt are in arc shape. We inlaid the column bar of drum with UHMW-PE (ultra high molecular weight polyethylene) materials which have a good wear-resistance performance.
5.Driving device:
Speed reducer + Variable speed controller
6.Evaporator and fan:
Both the fins and tubes are made of aluminum alloy. The frame structure of evaporator is made of food grade stainless steel. The air-box of axial fan is made of food grade stainless steel while the fan blades are made of aluminum alloy.
7.Belt tension device:
We adopt floating axle weight as belt tension device. The tension degree of conveyor belt can be adjusted.
8.Water slot (water plate) and drainage design:
The water slot will be installed on top of floor panels. It is made of food grade stainless steel. The water slot has proper slope to facilitate water discharging and avoid defrosting water penetrating into the floor panels.
9.Inlet device and outlet device:
Both the inlet device and outlet device are made of food grade stainless steel.
10.Control panel:
We adopt Schneider or Siemens electrical components.



The best IQF freezer for quick freezing all kinds of fruit & vegetable and some of the seafood.
Adopts the two stage belting structure---fristly, quick-cooling stage. Secondly, deep-freezing stage. Independently speed control system, and the speed of the two meshbelts can be changed infinitely.

1.Quick-cooling stage---the food particles are to be quick cooled after entering into the blast room. The surface of the particles would frozen and reach the temperature of 0 C. meanwhile, with the help of the striking chain, the particles would neither stick together nor sticke on the stainless steel meshbelt.

2.Deep-freezing stage---the food is to be moved on a stainless steel meshbelt, the foodstuff layer loosens with the increasing of the airflow. Some of the foodstuff particles become floating(this is the reason why this equipment is not applicable to big bulk foodstuff) when the air pressure reaches a certain scale, which brings interspace among the foodstuff particles, that is the way the fluidized bed come into being.
The floating particles frozen quickly and individually because they are blowing with strong cool air from all directions.

spiral freezer Descriptions,
Evaporator, adopts the aluminum tube coated with aluminum plate, unique alternative fin space design,which helps to prolong the deforsting time.
Heigh pressure fan, to guarantee the foodstuff to stay floating and prevent the particles from sticking together
Standard heat preserving board, quickly assembled, combined closely,superior heat preserving effect
Evaporative temperature, -40C
Condensating temperature, +35C
Deforsting: water
Defrosting time:every 8-12 hours, last no more than 2 hours each time
Electronic control panel, control the speed of the meshbelt, processing time, display the running speed and inner temperature.
