この発明は、食料品の連続急速凍結装置に関
し、より詳細には低温輻射手段を有する食料品の
連続急速凍結装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a continuous quick-freezing device for foodstuffs, and more particularly to a continuous quick-freezing device for foodstuffs having low-temperature radiating means.

Conventional freezing equipment is of the type in which an endless belt for transporting metal trays is installed on a copper plate with cooling means such as cooling coils. There is also a type that combines an endless steel belt with cooling means and a blower cooler.
がしかし、前者のタイプのものは金属トレイを

なり自動化が生かされないことになり、省力面か
ら見ると非常に不合理なシステムとなつていた。
さらに品質面から考えてもフリーザ前後で被凍結
物が停滞するため、温度上昇による汚染原因とな
つていた。 However, since the former type moves a metal tray over the copper plate, moisture in the air adheres to the entire surface of the copper plate in the form of powder snow, which reduces the freezing efficiency of the frozen object due to thermal resistance. It was causing a problem. In addition, since the objects to be frozen can only be transported after being arranged on the metal tray, de-plating is required even after freezing, making automation unusable, making the system extremely unreasonable from a labor-saving perspective.
Furthermore, from a quality perspective, the frozen material stagnates before and after the freezer, causing contamination due to temperature rise.

ビン、ヘモグロビンがメトミオグロビンとなり、
暗赤色や褐色に変質する原因となつていた。 On the other hand, the latter type of freezing method uses heat conduction and convection heat transfer, so the air flow velocity hitting the frozen object is high, and furthermore, there is a temperature difference between the air at the entrance and exit of the refrigeration equipment and the air at the center of the equipment. It promotes the drying of the frozen material and also promotes the oxidation reaction, for example, myoglobin and hemoglobin contained in the flesh of meat, tuna, etc. become metmyoglobin,
This caused the color to turn dark red or brown.

In view of the above circumstances, this invention places objects to be frozen on a cooled endless steel belt, etc., which is a conveying means, and freezes the objects by heat conduction from the bottom surface, and uses airless low temperature radiation means to freeze the objects. This was done based on the fact that if the air temperature around the object is cooled to below the temperature of the top surface of the conveying means, it will be possible to freeze the entire surrounding area, which will be extremely useful in preventing oxidation and deterioration of the object to be frozen. It is.

１４に流すように構成されている。 The cooling means includes a cooling plate 13 made of a material with good heat conductivity such as a metal or alloy having a smooth upper surface and provided so that the conveying means 3 can slide on the cooling means; The refrigerant, such as fluorocarbon gas, antifreeze, or liquefied gas is made to flow through the pipes 14 depending on the set temperature range.

In addition to the method of cooling the low-temperature radiation means 4, in addition to the method of installing the cooling pipe 16 on the metal plate 15, there are other methods such as forming a refrigerant path on the metal plate 15 and flowing the refrigerant, etc.
Various methods are possible. Furthermore, the low-temperature radiation means 4 is configured such that the gap between the low-temperature radiation means 4 and the conveying means 3 can be adjusted or fixed at a desired position.
尚、冷媒等は別装置（図示せず）により冷却さ
れる。 Note that the refrigerant and the like are cooled by a separate device (not shown).
次に、この発明の食料品の連続急速凍結装置の
使用状態について説明する。 Next, the usage conditions of the continuous rapid freezing device for foodstuffs of the present invention will be explained.
先ず、駆動ロール７を回転させると、エンドレ

少なくとも入口５の前方近傍で所望の温度にな
る。 First, when the drive roll 7 is rotated, the endless belt-shaped conveying means 3 moves from the inlet 5 toward the outlet 6, quickly comes into contact with the smooth surface of the upper surface of the cooling plate 13, and slides smoothly. Therefore, the conveying means 3 is rapidly cooled by the cooling plate 13,
The desired temperature is reached at least near the front of the inlet 5.
次に、原料加工工程のベルト１１によつて搬送

状態で熱が奪われ被凍結物１表面温度が急速に下
げられて凍結される。 Next, the object 1 to be frozen transported by the belt 11 in the raw material processing step falls onto the transport means 3, is transported into the freezing box 2, is frozen from the contact surface with the transport means 3, and is frozen. The low-temperature radiating means 4 provided in the box 2 also removes heat from the surroundings without wind, rapidly lowering the surface temperature of the object 1 and freezing it.
凍結された被凍結物１は、さらに、搬送手段３
上を搬送されて包装加工工程ベルト１２上に落下
し、次工程へと進行され製品となる。 The frozen object 1 is further transferred to a conveying means 3
It is conveyed above and falls onto the packaging process belt 12, where it progresses to the next process and becomes a product.
ところで、搬送手段３に載置されている被凍結
物１は、凍結中に搬送手段３に接着することはな
い。この理由は不明であるが、搬送手段３を一定
温度以下に冷却すると、被凍結物１は搬送手段３
に接着しない。従つて、凍結された被凍結物１
は、従動ロール８を通過した後、搬送手段３から
難無く落下し包装工程のベルト１２上に落下す
る。 By the way, the object to be frozen 1 placed on the conveyance means 3 does not adhere to the conveyance means 3 during freezing. Although the reason for this is unknown, when the conveying means 3 is cooled to a certain temperature or lower, the frozen object 1 is transferred to the conveying means 3.
Do not adhere to the Therefore, the frozen object 1
After passing through the driven roll 8, it easily falls from the conveying means 3 and onto the belt 12 of the packaging process.
尚、仮に被凍結物１が搬送手段３に接着して
も、搬送手段３が従動ロール８に沿つて湾曲する
ので、被凍結物１は簡単に搬送手段３から剥離脱
落する。 Even if the object 1 to be frozen is adhered to the conveying means 3, the object 1 to be frozen easily peels off from the conveying means 3 because the conveying means 3 curves along the driven roll 8.
ここで被凍結物１の品質の低下、例えば肉等の

中に含まれている分子中のFeが２価から３価に
変化し褐色を呈してくる。この褐色の程度が50％
を越すと肉等の色調は褐色になる。 Here, to explain the mechanism of deterioration in the quality of the frozen object 1, such as discoloration of meat, etc., myoglobin, which is normally contained in reddish-purple meat, becomes oxidized when oxygen is lightly bound to it. It turns into myoglobin and the flesh becomes bright red in color. Furthermore, when oxygen is strongly bound, that is, oxidized, oxymyoglobin changes to metmyoglobin, and the Fe in the molecules contained in the meat changes from divalent to trivalent, giving it a brown color. The degree of this brown color is 50%
If the temperature is exceeded, the color of the meat will turn brown.

なるようにコントロールすれば、肉等の変色を最
小限にすることが可能となる。 The mechanism by which myoglobin changes into metmyoglobin, that is, the influencing factors of oxidation, can be considered to be the temperature of the frozen object 1, pH, oxygen partial pressure, salt concentration, light rays, etc. Therefore, it is necessary to minimize these influencing factors. By controlling this, it is possible to minimize discoloration of meat, etc.
従つて、上述した構成を有するこの発明の食料

あるので、酸化することのない高品質の製品を製
造することができるものである。 Therefore, when the food product 1, such as meat, is frozen using the food product continuous quick-freezing apparatus of the present invention having the above-described configuration, the food product 1 does not dry, so that the salt concentration in the aqueous solution of the meat, etc. There is no increase in oxidation, the PH is low, and the conditions are ultra-low temperature and airless, making it possible to produce high-quality products that will not oxidize.

As is clear from the above description, the continuous rapid freezing device for foodstuffs of the present invention uses a combination of a conveying means 3 such as an ultra-low temperature steel belt and a low temperature radiation means 4, to prevent is kept at an ultra-low temperature by the low-temperature radiation means 4 in a windless state, and the surface temperature of the frozen object 1 can be rapidly lowered by removing heat from the frozen object 1. At the same time, freezing progresses from the entire surrounding area at the same time.
このため、従来の送風機付の冷凍装置と異なり

造することができる。 Therefore, unlike conventional refrigeration equipment equipped with a blower, it maintains an ultra-low temperature state with no wind and does not dehumidify, which prevents the product from drying out and minimizes changes in the salt concentration in the aqueous solution of the frozen object 1. Oxidation reactions can be suppressed, and decomposition reactions caused by microorganisms can also be suppressed, making it possible to produce high-quality frozen products, such as bright red, beautiful frozen meat products.

It has excellent effects.
