DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a freezer for continuously cooling and freezing foods, and more particularly to an energy-saving operation suitable for a large variety of small-quantity production, a small amount of energy, and a small volume. The present invention relates to a continuous transport type tubular freezer for business use, which is excellent in installation economics due to construction.

[0002]

^2. Description of the Related Art A conventional continuous transport type freezer for business use has a rectangular cross section perpendicular to the transport direction, and has a freezer chamber opening area of 6 m ² or more and a length of about 12 to 30 m. A single transfer net conveyor for continuous transfer is provided, and a plurality of cool air circulation devices including a freezing unit and a blower are provided at the upper or lower part of the transfer net conveyor in the freezer chamber. A large-sized one that circulates cool air inside the freezer room and has a CIP cleaning pipe inside to enable cleaning and sterilization, and to process a large amount of objects to be cooled or frozen (one-way configuration) It has become.

[0003] In order to quickly process moist fish meat without freeze-bonding of frozen products by lamination, a large freezer chamber equipped with a long one-way transfer net conveyor is required. To solve the problem, a return type two-stage freezing device has also been developed (Japanese Patent Publication No. 55-55).
36904).

[0004]

However, the above-mentioned conventional one-way continuous transport type industrial freezer is convenient when cooling and freezing of a large amount of the same food is always required. When cooling and freezing of various kinds of food to be processed are required, especially for small and medium-sized enterprises, the equipment is large and requires a large installation space, the equipment cost is expensive, There is a problem to be solved in that not only does the production line need to be changed each time the type of varieties are changed, but also the operating efficiency is reduced due to the processing of a small amount of food to be processed by a large freezer.

Further, in the conventional two-stage freezing apparatus, the food processing line cannot be set linearly because the transfer inlet and the transfer outlet of the food to be processed are on the same side.
Also, although the installation space is smaller than the former one-way device, it is very large as a cooling and freezing processing device for small quantities, various kinds of foods to be processed, so for small and medium-sized enterprises etc. Problems such as insufficient profitability in terms of cost, setting of a production line, and operation efficiency have arisen.

Further, in addition to the increase in size, with the enforcement of the PL law (product liability law), foreign matter is generally required for food production, processing, and processing machinery, and is contaminated, adhered, adhered to, and proliferated by microorganisms. CIP cleaning to ensure the prevention of contamination
The provision of the steam sterilization apparatus further increases the size and complexity of the apparatus, resulting in an increase in cost.

[0007] The present invention is excellent in strength and copes with temperature changes at the time of temperature rise, and is most suitable for cooling and freezing of small quantity and various kinds of foods to be processed. Continuous operation-type commercial freezer that can cool and freeze different foods simultaneously with the same freezer as well as cooling and freezing processing of a single food by reducing the volume and energy saving operation To reduce equipment costs, reduce installation space,
It is an object of the present invention to improve the operation efficiency, visually confirm the state of washing in a freezer room, ensure hygienic quality of food to be treated, and provide it at a low cost.
