Product use
The tunnel freezer can freeze single or dish products of multiple shapes and types quickly, effectively and economically and realize continuous entry and output of products for assembly line processing. The tunnel (plate belt) quick freezer is used mainly in quick freezing of meats, aquatic products and Certain fruits and vegetables; the tunnel (mesh belt) quick freezer is used mainly in quick freezing of prepared foods including dumplings, stuffed bun, rice dumplings, etc. as well as single or dish meats and aquatic products.
Compared with common plate belt freezers and mesh belt quick freezers, the high-efficiency tunnel freezer is characterized by short freezing time and high freezing quality. The equipment is unsuitable for quick freezing the easily deformed foods such as bread fish, bread shrimp, etc.
Core features of the product
The product Introduces the core technology of TOYO's patent quick freezing technology--"thermal fluctuation" air distribution system, so that high-speed uniform cold air currents are sprayed onto food surfaces in "pulsing mode", and food surfaces are under the alternate action of vertical wind with vortex wind, thereby realizing quick and continuous heating between cold air currents and food surfaces and between food surfaces and food centers, effectively increasing food freezing speed and greatly improving food freezing quality.

Structure form and features
The tunnel freezer consists of feed inlet, insulation structure, discharge gate, conveyor belts, transmission system, evaporator, fan and electric control system. In terms of the number of conveyor belts, the tunnel freezer includes multiple forms such as single plate belt, single mesh belt, dual plate belt, dual mesh belt, etc. In the dual plate belt quick freezer or the dual mesh belt quick freezer, an insulation structure is separated by insulation boards into two relatively independent quick freezing spaces, which are fitted with two sets of completely independent transmission systems and air distribution systems. This greatly shortens the length of the processing workshop on the premise of meeting the customer's requirements for processing techniques and quality.
Insulation structure
The insulation structure is assembled of two-sided stainless steel rigid polyurethane laminboards and supported by an integral rigid bottom frame and has excellent heat retaining property.
Uses the environment-friendly material R141B as a foaming agent, thus both protecting environment and obtaining excellent heat retaining property.
The feed inlet and discharge gate are assembled of two-sided stainless steel rigid polyurethane laminboards, thereby effectively preventing cold leakage and saving energy.
In order to thoroughly discharge the accumulated water, the bottom board is inclined to a certain angle integrally; for the single plate belt freezer and the single mesh belt freezer, the bottom board is inclined towards one side; for the dual plate belt freezer and the dual mesh belt freezer, the bottom board is inclined from the middle towards the two sides.
The freezer can be placed on a plane or the ground with drainage slope directly and stably without need to set up a foundation, thus making for ground cleaning.
Universal bun foots of adjustable height are installed and their height can be adjusted within a certain range according to the actual conditions of the installation site.
Evaporator
Structure form with aluminum tubes and aluminum sheets, combined defrosting mode with water +hot ammonia, conforming to food hygiene and safety requirements.
Large size fins, imported special equipment for expanded connection, tight contact, small heat resistance, high heat exchange efficiency.
Variable pitch of fins and the optimum air current organization form so as to realize long-term continuous working with high efficiency.
The liquid feed device and air return device use TOYO's patent technology, thus preventing oil from being accumulated in coil pipes.
Conveyor belts
The conveyor belts use high strength stainless steel plate belts and their tensile strength and surface hardness are considerably improved. The linear wave degree and linear bending of the plate belts are far lowered. and the plate belts have become the stainless steel conveyor plate belts with the best quality on the international market at present.
The belt plate surface with high hardness is neat and also has long service life, high load bearing capacity and more extensive applicable scope of frozen products.
The surface is flat, thus ensuring operation stability; in addition, a plate belt centering device is installed so as to thoroughly eliminate off-tracking of plate belts.
Full stainless steel mesh belts are made using imported CNC mesh belt forming machines . Multiple shapes of mesh belts including "diamond-shaped" ones, "herringbone" ones, "in-line" ones, etc. can be selected to ensure perfect appearance of foods. The mesh belt backing strips from precision casting of new materials reduce mesh belt wear and result in longer service life.
A high-efficiency cleaning device is set up at the feed inlet to thoroughly clean belts and avoid the growth of bacteria; in addition, water scraping and deicing devices are set up accordingly to protect belts from being damaged.
