Definition of Spiral Freezer
In the food processing industry, spiral freezers, also known as spiral freezing machines, play a crucial role in preserving the quality and freshness of various food products. As spiral freezer manufacturers, we understand the importance of these machines and are here to provide you with an in-depth look into their components, types, and how to choose the right one for your needs.
A spiral freezer is a high-efficiency, energy-saving rapid freezing equipment that uses a spiral conveyor system to transport food products through a refrigerated chamber. This process ensures that food is evenly and quickly frozen, maintaining its nutritional value, texture, and flavor.
Types of Spiral Freezers
Several types of spiral freezers are available in the market, each designed to meet specific needs and applications. Some common types include:
Single-Spiral Freezer: This type of freezer is suitable for smaller-scale operations. It features a single spiral conveyor that moves food through the freezing chamber.
Double-Spiral Freezer: Designed for larger-scale production, this freezer has two parallel spiral conveyors, increasing the freezing capacity and efficiency.
Self-stacking Spiral Freezer: This freezer is suitable for single-freezing various granular and block products. The design feature of the Self-stacking Spiral Freezer is that the products are stacked layer by layer through the self-stacking conveyor belt to form a spiral structure, making full use of the space and improving the freezing efficiency.
Components of Spiral Freezers
Conveyor System
Transmission motor: provides power to drive the operation of the entire system.
Mesh belt: used to carry and transport food to be frozen, usually made of high-strength SUS304 stainless steel mesh wire, with higher tensile strength and fine workmanship.
The unique three-chain structure increases the effective area of the mesh belt and fundamentally solves the problem of belt flipping. Ribs on both sides ensure that the food is not easy to fall and is safer to use.
Turret: In the double spiral quick freezer, the turret supports and rotates the mesh belt to ensure the food can be frozen evenly and continuously through the evaporator.
Independent inverter: used to adjust the speed of the transmission motor, thereby controlling the mesh belt’s conveying speed and the food’s freezing time.
Evaporator
Structure: The evaporator is composed of stainless steel and aluminum fins, arranged with variable fin pitch to ensure smooth air circulation. The evaporation pipe can be an aluminum tube or copper tube.
Function: The evaporator is one of the core components of the spiral quick freezer. Its main function is to reduce the temperature of the refrigerant and evaporate it, thereby absorbing the heat from the surrounding environment to achieve the purpose of freezing food. The evaporator of the spiral quick freezer adopts the outer wall tube plus the internal pre-cooling method, which can freeze food quickly and evenly.
Storage Board
Material: The storage board is made of stainless steel, with excellent corrosion resistance and strength.
Insulation effect: The insulation storage board is made of double-sided stainless steel SUS304 polyurethane integral foaming, and the density of the insulation board is 42kg/m³; convex and concave groove installation, eccentric hook connection, strong insulation effect.
Design features: The storage body is equipped with an inspection door with a low-voltage electric heating device to prevent freezing, which is safe and reliable; there is also an inspection channel in the storage for easy cleaning and maintenance.
Electrical device
Composition: The electrical system consists of a stainless-steel electric box and an intelligent control device.
Function: The electrical device is responsible for controlling the operation of the entire spiral quick freezer, including the start, stop, and speed regulation of the transmission motor, the refrigeration control of the evaporator, and safety protection.
Choosing the Right Spiral Freezer
When selecting a spiral freezer, consider the following factors to ensure you choose the right machine for your needs:
Production Capacity: Determine the volume of food you need to freeze per hour to select a freezer with the appropriate capacity.
Product Type: Different types of food require different freezing conditions. Choose a freezer that can accommodate the specific needs of your products.
Energy Efficiency: Look for a freezer with high energy efficiency to reduce operational costs and environmental impact.
Maintenance and Service: Choose a manufacturer that offers comprehensive maintenance and service support to ensure the long-term performance of your freezer.
