Comparison of IQF tunnel freezer and traditional Blast freezing chamber (cold room)

With the gradual improvement of the market’s quality requirements for frozen products, more and more customers of quick-freezing warehouses have begun to use IQF equipment for quick-freezing. IQF equipment has many advantages such as short freezing time, high freezing quality and continuous production.

Comparison of IQF tunnel freezer and traditional Blast freezing chamber (cold room)
Project	Comparison item	Blast freezing chamber	Mesh belt tunnel freezer
Product	Picture
Structural difference	Ground requirements	The ground should be insulated, wear-resistant, air- and waterproof	Level ground
	Space requirement	Occupies a large plane and height, generally the net height is not less than 3 meters	There is no much requirement for space and height. The width of this quick freezer is 1.5M*2.5M*12M
	Installation cycle	2-3 weeks (excluding civil construction and floor maintenance)	2-3 weeks
	Defrost effect	Dripping water or temperature rise of the storage will affect the product	No effect
	Automatisation	Manual inbound and outbound	High automation, automatic feeding and discharging
	Maintenance	Normal	Normal
	Labor intensity	High	Low
Quick freezing quality and operation comparison	Freezing temperature	-28℃ to -35℃	-28℃ to -35℃
	Freezing time	12-24 hours	30-45 minutes
	Food safety	Unsatisfactory or hidden danger	Safe
	Product quality	Poor	Good quality
	Project costs	Low	High
	Energy consumption	Normal	Normal
	Hardware matching	Low-temperature cold storage room(optional)	Low-temperature cold storage room (required)
Summary	1	The faster the freezing time, the higher quality of the frozen product.
	2	Equipped with a tunnel freezer, a low-temperature cold storage room is also required. The initial investment of a tunnel freezer is about 2-3 times larger than the investment cost of using a blast freezing chamber.
	3	Due to its own structure, all products are moved in and out of the blast freezing chamber by manual handling. The labor cost is relatively high and the efficiency is not high.
Conclution	1	Customers who have very limited budget and only need to meet the general process requirements can choose blast freezing chamber.
	2	Customers who has suitable budget, and pursue high-quality products can choose tunnel freezer.
	3	Quick-freezing machine instead of blast freezing chamber is the inevitable trend of enterprise development and growth. Because of the quality of frozen products, automation (manual consumption) and process controllability, quick freezers have absolute advantages.
