Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a continuous work-type cooling and solidifying apparatus for a liquid workpiece which obtains a band-like or plate-like solidifying member from a liquid material such as curry roux, stew roux or juice freeze.
[0002]
[Prior art]
For example, in the case of Carreru, animal oils and fats, wheat flour, seasonings, spices and the like are mixed and heat-treated in appropriate amounts to form a liquid, poured into a mold, cooled and solidified, and shaped and solidified into a strip or plate.
In the case of freezing juice, etc., the extract or concentrated liquid is transferred to the freezing step and pulverized and dried. In the previous step of the drying step, quick freezing to a thickness of several millimeters on a moving stainless steel belt is performed. It is carried out.
[0003]
The above mold casting method is a batch type, so it takes time to fill the mold container with the liquid work, which not only takes time to move to the next process after solidification but also causes poor raw material yield and high cost. Form.
[0004]
In addition, as a conventional example A in the case of a continuous shaped cooling and solidifying apparatus for a liquid work, an invention of a continuous production apparatus for a belt-like gel material described in Japanese Patent Publication No. 4-57316 can be given.
The present invention relates to an apparatus for continuously forming a band-like gel using a packing belt for shaping, and cooling and solidifying the band-like gel, and cooling and solidifying the sol-like liquid while shaping the band-like gel Things are obtained continuously.
As shown in FIGS. 5 (A) and 5 (B), the continuous production apparatus for the belt-like gel material has an opposing surface in the same direction with an appropriate interval between the work conveyor 50 and the upper part of the conveyor 50. And the opposing conveyor 51 which travels at the same speed is provided horizontally,
A pair of packing belts 52, 52 sandwiched between the transport conveyor 50 and the opposing conveyor 51 and rotated in synchronization with the transport conveyor 50 are provided, and the interval Y is set to a dimension corresponding to the width of the workpiece. A space 53 having the same space dimension is formed from the beginning to the end of the conveyor by the conveying conveyor 50, the opposing conveyor 51, and the packing belts 52 and 52, and the gel by cooling is conveyed while transporting the sol-like liquid injected into the space 53 A band-shaped solidified member having a uniform width Y is formed by shaping.
[0005]
Moreover, the thing of the structure shown to FIG. 4 (A) and (B) is mentioned as another prior art example B of the said continuous shaping cooling solidification apparatus of the said liquid workpiece | work.
That is, as shown in FIGS. 4A and 4B, the apparatus shown in the conventional example B brings the opposing surfaces into contact with the workpiece carrying conveyor 55 and the left and right workpiece mounting surfaces of the steel belt 60 of the conveyor. In addition, two sets of left and right coaxial guide conveyors 56 and 57 that rotate in the same direction and at the same traveling speed are provided, and the guide conveyors 56 and 57 adhere a thick elastic belt member 58 to a narrow toothed belt, The inner interval Y is made to correspond to the shaped width dimension of the workpiece, and the liquid workpiece member is injected into a rectangular space having a width dimension Y regulated on three sides by the conveying conveyor 55 and the guide conveyors 56 and 57 in the conveying process. It is solidified by cooling to obtain a belt-like solidified member having a width dimension Y.
[0006]
By the way, in order to obtain a belt-shaped solidified member having a certain width by shaping the liquid work by cooling on the conveyor,
a, the liquid work injection member does not leak from the contact surface between the packing belt 52 and the elastic belt member 58 and the conveyor, which regulate the width,
b, the distance Y between the packing belt 52 and the elastic belt member 58 for regulating the width dimension of the workpiece is always constant from the beginning to the end of the dimension regulation;
However, in the conventional examples A and B, the occurrence of a gap has a structural defect that tends to be particularly noticeable in the middle part of the conveyor. Therefore, it is conceivable to increase the degree of pressing, but conversely, the belt meanders left and right, and the position of the rectangular space into which the liquid workpiece is injected is determined. There is a problem of causing a deviation and a fluctuation of the regulation width Y.
As described above, in the conventional example, it cannot be said that the problem of liquid leakage is sufficiently solved.
[0007]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a continuous leveling cooling and solidifying apparatus for a liquid workpiece that has a leveling guide that does not leak and has a constant regulation width.
[0008]
[Means for Solving the Problems]

In a continuous transfer cooling device provided with a work transfer conveyor disposed in the longitudinal direction of a horizontally long casing surrounded by a heat insulating wall, and a work cooling means,
The conveyor is composed of a steel belt, and a liquid workpiece injection part and a shaping guide are provided at the entrance of the belt,
The shaping guide is composed of a pair of parallel weir conveyors having the steel belt work mounting surface as a traveling side surface. The facing distance of the weir belt of the conveyor corresponds to the work width and is the same speed and the same as the steel belt. It is characterized by having a configuration in which it travels in a liquid-tight manner in the direction.

With the above-mentioned configuration, a cooling storage body composed of a horizontally long casing surrounded by a heat insulating wall is prepared, and a work conveying conveyor is provided in the longitudinal direction to form a continuous cooling device, and a liquid work is placed above and below the conveyor. A cooling means for solidifying is provided, and a liquid work injecting portion is provided at the entrance of the conveyor, and a shaped guide for regulating the width direction when the work is solidified is provided on both sides, so that the liquid work is solidified to a certain width. A band-shaped solidified member can be obtained continuously.
In addition, since a steel belt is used for the conveyor, liquid leakage due to internal squeezing from the mounting surface of the liquid workpiece is prevented, and efficiency from the bottom of the liquid workpiece due to direct contact via the mounting surface is reduced. Cooling is possible, and the belt can be efficiently cleaned against contamination of the belt due to the loading of the liquid workpiece, thereby enabling efficient conveyance of the liquid workpiece.
[0010]
In addition, the configuration of the above-described shaping guide satisfies the necessary conditions of the shaping guide that prevents liquid leakage and is a constant regulation width, which are the main problems of the present invention.
In other words, the shaping guide is composed of a pair of weir conveyors provided in parallel so that the traveling side surface is in liquid-tight contact with both sides of the liquid work mounting surface of the steel belt. This is a structural solution to the generation of gaps, and the problem of making the regulation width constant can be solved without damaging others by applying high tension to the belt.
In order to increase the contact area between the weir belt and the steel belt provided on the weir conveyor, a thick belt is used for the weir belt, and an elastic member is attached to the contact part, which causes liquid leakage. Can be completely removed.
[0011]
According to a first aspect of the present invention, there is provided a work cooling means comprising a flat tank for lower surface cooling of an upper steel belt on which a liquid work is mounted and an air cooler for cooling the inside of the casing.
[0012]
Since a flat tank having a metal flat plate on the cooling surface is used for cooling the lower surface of the steel belt, it is possible to efficiently impart cold heat to the steel belt. The upper surface of the liquid workpiece is cooled in a low temperature atmosphere by the air cooler.
[0013]
Further, the work cooling means according to claim 1 may be constituted by a cold air jet cooling section for cooling both the upper and lower surfaces of the upper steel belt on which the liquid work is mounted.
[0014]
In addition, the liquid workpiece injecting portion according to claim 1 is provided with a liquid-tight stopper member for preventing external outflow during injection.
[0015]
Moreover, the length of the shaping guide according to claim 1 is characterized in that the liquid workpiece is set to a substantially solidified state.
[0016]
