[0002]

2. Description of the Related Art Conventional methods for continuously freezing general foods using a belt conveyor as a conveying means include, for example, a low-temperature liquid (for example, calcium chloride brine or the like);
・ Hereinafter referred to as low-temperature brine) Double contact method using double contact belt (freezer) b Single contact method using low-temperature brine and cool air [steel belt freezer] c Cycling and forming a parallel flow of freezing air on a belt conveyor Freezing method using only cold air [Steel Belt Freezer "Tunnel Freezer" (trademark)] d Spray of low-temperature liquefied gas such as liquefied nitrogen or liquefied carbon dioxide, and liquefied gas that is rapidly frozen using its latent heat of vaporization and sensible heat Freezing methods and the like are known.

[0003] Of these known quick freezing methods, a and b both use low-temperature brine, and a makes the lower surface of the food to be frozen contact the low-temperature steel conveyor surface, This is a method in which a low-temperature brine is covered with a thin-film container that is circulated and brought into contact with the thin-film container to perform contact freezing from almost the entire surface of the food to be frozen. It is cooled by low-temperature brine from the bottom, and the top surface of the frozen food is frozen by the circulation of auxiliary cold air, so it is possible to freeze in a relatively short time regardless of the shape of the frozen food. However, not only are initial costs and running costs high, but also heat transfer is hindered by the air film covering the upper surface of the frozen food, cooling and There is a problem in it affects the sintering process time.

[0006]

In order to solve such a problem, hot air, hot air or hot air is applied to a conventionally processed material (object to be processed), for example, a snack confectionery or a bread crumb material.

That is, according to the above conventional processing apparatus,
The aeration process can be performed efficiently in a short time. However, such a factor of the efficiency of the aeration process not only increases the chance of contact with the jet air due to the disturbance of the object to be processed, but also increases the efficiency of the process. The purpose is to destroy the air film (temperature boundary layer) formed on the surface of the object and improve the heat transfer coefficient. In particular, the air film formed on the surface of the object is destroyed, and the object is cooled. The issue is how to perform the freezing and freezing economically and efficiently, and how to use the above-mentioned reference technology in a food quick freezing processing apparatus.

Five)
This is a hybrid quick freezing method for soft soft foods such as ice cream which is circulated back to the soft food.

A hybrid quick freezing apparatus for soft soft foods such as ice cream is composed of a pre-cooling freezing chamber (1) surrounded by heat insulating walls and a plurality of horizontally long main freezing chambers (2). An endless conveyor (3) consisting of a steel conveyor that conveys, in each room, a frozen food (F), which is a soft food such as ice cream with a surface that is soft and easily deformed by melting. The pre-cooling and freezing chamber (1) is provided with a liquefied gas spray header
(11), the liquefied gas spray header (11) is connected with a gas supply pipe from a liquefied gas supply tank (12), and an indoor circulating blower (13) for controlling temperature and an exhaust port (14). The configuration is provided.

[0014]

According to the hybrid quick freezing method and apparatus for soft soft foods such as ice cream according to the present invention, the surface of the food to be frozen (F) is frozen by liquefied gas spray freezing means. Following the pre-cooling freezing chamber (1) to be passed, the inside of the horizontally long main freezing chamber (2) was continuously passed at a predetermined speed, so that the food to be frozen contained air bubbles and the like inside. The surface is frozen in a very short time as it is. As a result, this surface frozen layer acts as a barrier against external wind pressure due to cold air injection during the actual freezing afterwards, and the barrier acts as a barrier preventing escape of internal air bubbles and the like during shrinkage due to the actual freezing, and No defective products due to deformation, damage, etc. of the product are generated.

In addition, the liquefied gas spray freezing means is used for the frozen food (F) not only in the liquefied gas freezing means but also in the pre-cooling stage before the main freezing treatment by cold air injection, thereby achieving the above-mentioned effects. As a result, efficient pre-cooling by using a small amount of expensive liquefied gas and shortening the freezing time as a whole can reduce the pre-cooling freezing chamber (1) to a plurality of horizontally long main freezing chambers (2). On the other hand, when the food to be frozen (F) is a soft food such as ice cream, the food can be connected and removably used.

Further, a conveyor for transport in the freezing chamber (2)
The cool air circulation unit moves from the horizontal position where the forward movement of (3) intersects the transport direction up and down to the transport conveyor (3).
By vertically jetting the cool air supplied from (5), if the conveyor (3) is a steel conveyor, the cool air injected from above impinges on the surface of the frozen food (F) due to the collision of cool air injected from above. The air film (temperature boundary layer) is destroyed and is directly cooled efficiently, and the back surface of the food to be frozen (F) is transported through the conveyor (3) by spraying from below or circulating cool air. Indirect cooling and contact freezing, and the suction side of the cold air circulation unit (5) is opened inside the freezing chamber for recovery. Since the circulation passage is formed, freezing of the frozen food (F) becomes extremely efficient, compared with the conventional freezing means employing the means for collecting the cool air jetted from above without being circulated from the periphery of the jetting part, Rapid freezing Processing can be achieved.

Further, by flowing the cool air after the injection into the main freezing chamber (2) so as not to affect the jet injection by back pressure or the like, the cool air is returned to the cool air circulation unit (5) and circulated. In addition to effectively acting to cool the entire inside of the freezing chamber (2), the energy for cooling the air with the air cooler (51) of the cool air circulation unit (5) is smaller than that of the liquefied gas freezing means. This greatly reduces the cost, which can greatly contribute to the reduction of running costs.

Therefore, despite the jetting of cool air, the time required for freezing can be reduced without causing deformation and damage of the food to be frozen (F) due to the wind pressure, and economical use of cold air is possible. As a result, it is not only optimal for cooling and quick freezing of frozen food (F), which is soft food such as ice cream, but it also enables the miniaturization and efficient operation of the equipment, resulting in lower equipment costs. It is possible to provide a hybrid quick freezing method for soft soft foods such as ice cream, which can reduce initial costs and running costs due to downsizing, installation space reduction, and the like, and an inexpensive apparatus. .

According to a fourth aspect of the present invention, the injection port of at least the upper cold air injection pipe (7) and the conveyor for conveyance are provided.
The height of the frozen food (F) can be changed and adjusted in accordance with the thickness of the frozen food (F) or in accordance with the thickness and the transporting speed of the frozen food (F). ) Can achieve high rapid cooling or rapid freezing efficiency corresponding to the size.

Furthermore, by making the horizontal cross section of the main freezing chamber (2) a hexagonal shape having vertical walls on the left and right sides, it is easier to transport and the like and has a smaller installation area than a cylindrical type. And the inner bottom of the main freezing chamber (2) is formed into a groove by corners, and the inside of the main freezing chamber (2) is cleaned and
Since the flow of the washing liquid by the equipment to be sterilized (for example, CIP washing / sterilizing equipment) is guaranteed and no pool is formed, the sanitary management of the quick-freezing equipment and the sanitary management of the frozen food (F) can be systematically managed. , HACCP (Hazard Analysis of Food to be Frozen, Critical Control Point Method).
