Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a freezing device that continuously freezes a product to be imitated.

Conventionally, there has been a device of this type as shown in Figure O1. In the figure, +11 is a black steel belt made of a single piece of stainless steel with a smooth surface.
This steel belt (11 is the product number exhibition (11) side [,
The steel belt (1) is moved by a drive pulley (3) driven by a variable speed motor (not shown), and the moving speed of the steel belt (1) is controlled by the speed control of the variable speed motor. Adjustments are made.

(2) is a steel pel) which is placed on the product supply port QQ) side with a tensioner that applies a constant tension to +11.

There is a brine tank (4) on the bottom of the steel belt (1).
are in contact with each other, and $ and frozen items (5) are arranged on the top surface. Furthermore, a cooling fin coil (6) and a fan (7), which are CIri airplast devices, are arranged above the cooling fin coil (6) and a fan (7), and the entire air circulation path is formed by the air distribution system (8).

These refrigeration zones (1 odor) are housed in the N'lijr/Be~ tunnel (9) and prevent heat from entering from the outside.

Circulate back and forth.

Father, the cooling fin coil (6) is also installed externally.
The refrigerant is supplied from the refrigerant (1611) and returns from the refrigerant outlet (1η) for excitation.

Next, the operation will be explained. Freezer product supply port (1
When the temporary St crystal (5) enters the steel belt 1] which moves at a constant speed, the product to be frozen (5) is cooled by the Nofline liquid in the Huffline tank (4) while entering the Teikoku zone. Contact freezing is performed via fi+.

On the other hand, for the upper surface of the crystal (5), refrigerant is supplied from a separately prepared external refrigerator through the tuning fork cooling fin coil (6) and fan (7) Wr fia, tunnel (9) Air distribution duct (8)
Airplast and freeze.

The product to be frozen (5), which has been completely frozen in this way, is cut into pieces (2) and all teeth (tunnel (9)) are transported to the next process.

Conventional freezing is depicted as above, so the Tl of the frozen product is rapidly frozen due to contact freezing, but since the cooling air is completely directly blown onto the top surface, the frozen product is reduced to a dry field. In addition to this, the cooling rate is slow, resulting in slow freezing, which can easily lead to a decline in product quality. In addition, since this device employs two methods, brine cooling and air blast cooling, it requires two kneading machines, which has the drawback of high initial cost and high running cost. Furthermore, a brine pump (not shown) was required for brine cooling (there was a drawback that it would be discarded and left behind).

This older brother' was made in 7th place to eliminate the drawbacks of the above-mentioned side floor type, and the first and second /< /L/
) A brine cooler that completely cools this cold brine is placed directly in front of the conveyor belt, and is immersed in the cold brine that cools the first and second belt conveyors. Conveyor: 1 car The purpose of the present invention is to provide an energy-saving freezing device that can properly freeze the frozen products that are conveyed by people and can omit the need for a brine pump that causes cooling loss.

Below, some examples of this example will be explained with reference to the drawings.

In Fig. 2, steel belt conveyor + o ty)
A flexible belt conveyor 411 is arranged at the top.

A cross section of the flexible belt conveyor (l) is shown in Figure 3. Flexible belt +22) is a product made by combining a rubber film with excellent flexibility and airtightness with a base fabric as a reinforcing agent and molding it together at low temperatures. Although it is worse, it can be overcome by completely reducing the thickness.

1231 F; l chain, (24) is a sprocket and flexible bell) +22) is a chain (the lower side of the flexible belt conveyor t21, which is housed in the edge, is filled with cold brine e281, 9 necessary minimum (The 28i has an upper brine cooler immersed in Cold Brine Co., Ltd.).
4 is a brine-saving (+a+ ic) immersed lower brine cooler, each of which functions as an evaporator of a direct expansion type refrigeration system.

Next, the operation will be explained. Freezer product supply port (1
When the product to be frozen (5) is placed in 0), the l of the steel belt conveyor (11 and 7 lexiple belt conveyor i2'l)
During this period, the plate frozen product (5) enters the freezing zone 021 while being sandwiched between the steel belts (5), whose lower surface is cooled by the steel belt conveyor +11 K, and whose upper surface is in contact with the flexible belt 122+, which is cooled by the cold brine 2L5. Because of this, heat conduction occurs quickly.

Even if one dimension of the product's shape changes, the flexible bell 112Z in contact with the product deforms along the shape as shown in Figure 3, so it always maintains a good state of heat conduction through contact with the product. can.

In this way, the product to be frozen f5) can be quickly frozen on both the upper and lower surfaces.

If hunting is a factor, it is possible to quickly fix the surface, which helps maintain freshness and improve quality during the distribution process.

The flexible belt 22) is pressed against the unloading crystal (5) and the steel belt conveyor (1) by the weight of the cold brine 12 (2), so it moves at the same speed as the steel belt conveyor + 11, so the flexible belt +
Is 2J necessary for tin rocket I24) and chain prisoner Hg movement? Only a small amount of force is applied.

The condensed products pass through the freezing zone (through I21) and are transferred to the single item collection section (If).
o Since 1" is wasted in the Cub IJ section (3), the product naturally leaves the steel belt conveyor] 1) and moves on to the next process.

In addition, in order to completely improve the performance of the upper brine cooler 127+ and lower brine cooler I28), the cold 7' line (13) I, 26) sound strength ii is installed by agitator (not shown).
It is also conceivable to flow it in an r'i manner.

In the above example, a case was explained in which two brine coolers: λη crabs were used. Supply circulation may also be used.
Compared to a brine pump that goes through the entire refrigerator, it can be used with a sufficiently small water head, so it requires less power.

As mentioned above, according to this lack of clarity, both of the two parts of the crystal are connected! Since I explained how to freeze the product, it is now possible to freeze the plate crystals at the breath rate, thereby maintaining the freshness and improving the quality of the frozen products. Furthermore, regarding the outfit and S, there are 7 lines in the cold dream of a straight set:
Since there is no need for a brine pump using a belt conveyor reed, an energy-saving type Nozuko-type freezing equipment can be installed.
