DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous transfer pipe type freezer for continuously cooling or freezing food.

[0002]

^2. Description of the Related Art A conventional continuous transfer type freezer has a freezer chamber opening area of a cross section perpendicular to the transfer direction at least 20,000 cm ² and a length of at least
A conveyor for continuously transporting the food to be treated is disposed in a freezer room of about 12 to 30 m, and a plurality of cool air circulation devices including a freezing unit and a blower are disposed above or below the conveyor in the freezer room. The cooling air is circulated in the freezer chamber to cool or freeze the food to be processed.

[0003]

However, the conventional continuous-conveying freezer described above, as is apparent from its size,
The height of the device is longer than the height of an adult (1.5 to 1.8m).
This is a very large device, which is convenient when cooling and freezing processing is always required for a large amount of the same processed food.However, cooling and freezing processing for a small number of multi-type foods to be processed are required. For small and medium-sized enterprises, especially because the equipment cost is high, a large installation space is required, washing and sterilization is required every time the food to be processed changes, and the operating efficiency is low. In order to reliably prevent contamination and contamination of food, such as contamination of foreign matter, adhesion, adhesion of microorganisms, growth, etc., which is generally required for food manufacturing machinery, further equipment is required. However, this has been complicated and has led to an increase in cost.

The present invention is most suitable for cooling and freezing of small quantities and various kinds of foods to be processed, and enables miniaturization and selective operation of the apparatus, thereby reducing the cost of the apparatus, reducing the installation space, and operating efficiency. Cleaning and sterilization after simplifying the freezer chamber, preventing contamination of foods with foreign substances, adhesion, adhesion of microorganisms, growth, etc., and sterilization in the freezer device can be performed reliably and easily. Another object of the present invention is to provide an inexpensive continuous transfer pipe type freezer for small and medium-sized businesses.

And a conventional cleaning control panel 42.
Same as IP cleaning means.

As described above, the three freezer units 1
The continuous transfer pipe type freezer according to the present invention having:
When three types of foods to be processed are continuously frozen,
Freezer equipment on the transport line for each food to be processed
It is installed and used so that part 1 is interposed continuously,
If there are two types of food to be processed, one freezer
The portion 1 is stopped, subjected to the freezing process by driving only the freezer apparatus part 1 of the second base, freezers are stopped
In the device part 1, each duct 3 connected to this,
4, the air flow control valves 23 and 24 are closed to stop the circulation of the cool air, and the CIP cleaning device 30 is not operated.

In the above-described continuous transport pipe type freezer, the freezer chamber 10 is washed by cooling or freezing the food as a freezer, and then spraying the inner wall of the conveyor 17 and the freezer chamber 10 by a spray nozzle (not shown). , A method of washing with warm water by spraying with warm water at 40 to 60 ° C, or washing with warm water, then spraying a solution with a detergent concentration of 2 to 3%, forming and washing, leaving for 10 to 15 minutes,

[0016]

Continuous conveying pipe type freezer of the present invention described above, according to the present invention, by constituting a pipe material in which a heat insulating wall structure, with the existing necessary length of stainless steel tubing or the like of the ready-made, the conventional Is very small compared to
Without a built-in cold air circulating device portion duck freezer compartment, also separately from the freezer unit portion, said freezer
Since the cooling air circulation path is formed by connecting the cooling air circulation duct on the upper part of the equipment part with a cooling air supply duct equipped with an air flow control valve and a cooling air suction duct, the freezer equipment part
And the cool air circulation unit are
Installation footprint usually results in death of the top of the freezer unit
The upper space, which is a space, is used as the installation space for the cool air circulation unit.
Can be used more effectively,
And a minimum space transfer path necessary for processing small quantities of food to be processed can be secured. Can be interposed.

Further , a cool air supply duct and a cool air suction duct are provided.
For each of the
The air flow control valve, which is controlled accordingly,
Te, a plurality of freezer using the same cold air circulating device portion

The cooling air circulation unit can be set in parallel with the cooling air circulation unit , or the freezer unit can be installed linearly and continuously if necessary.In this case, the cooling air supply duct and the cold air suction duct are provided. In addition, the air flow control valve can be controlled in response to the driving and stopping of the freezer device part , and the individual or all freezers can be driven, so that small-quantity, multi-product processing can be performed with good operation efficiency. be able to.

In the freezer room, a conveyor and a CI are provided.
Since P wash pipe is simplified configuration in which only exist, sufficient if cleaning a simple surface of the conveyor and the freezer inner wall surface, the control of the CIP cleaning device part, foreign material in food, deposited microorganisms Prevention of contamination such as adhesion and proliferation of bacteria and sterilization are surely performed.

Also, utilizing the same cool air circulation device portion ,
Since it is possible to circulate cold air through a plurality of cool air supply duct and the cold air suction duct to a freezer apparatus portion, the number of free in accordance with the type of processed food
The Heather device portion as cold air circulating device portion and set, and or a freezer unit parts as required can be added in series or in parallel, moreover, was provided in the cold air supply duct and the cold air suction duct, By controlling the air flow control valve, which is controlled in response to driving and stopping the freezer unit ,
Since the individual or all freezers can be driven, a small number of food products to be processed can be cooled or frozen with good operation efficiency.

Furthermore freezer compartment, since a structure in which the conveyor with the cleaning pipe is simplified only present, sufficient if cleaning a simple surface of the conveyor and the freezer inner wall surface, the CIP cleaning apparatus part, to food Prevention of contamination such as contamination and adhesion of foreign matter, adhesion of microorganisms, growth and the like, and sterilization can be reliably performed.

Therefore, according to the apparatus of the present invention, it is most suitable for cooling and freezing of a small number of foods to be processed in a large variety, and enables the apparatus to be reduced in size and selective operation, thereby reducing the apparatus cost and installing space.
