Description

Automatic Systolic Machine {AUTOMATIC SHRINKING APPARATUS}

The present invention relates to an automatic shrinker, and more particularly, to automatically heat-process and pasteurize a packaged food (working meat) vacuum-packed with a heat-shrink film in order to prevent meat contamination and deterioration during distribution of meat. It relates to a systolic machine.

The distribution method of meat is a trend that is branded and distributed in the form of refrigerated or frozen meat beyond the traditional method, that is, through the butcher shop. In order to distribute meat in the form of refrigerated or frozen meat, it is necessary to provide more hygienic and high quality meat, and packaging to prevent meat contamination and deterioration in the meat distribution process is one of the important processes. . The meat packaging method is made in a variety of ways, among which is widely used shrink packaging method using a heat shrink film.

Brief description of the heat shrink packaging process is as follows. First, the meat of cattle, pigs or chickens slaughtered through the shaping process is separated by portions, and the separated meat is placed in a heat shrink pack and vacuum-packed, and then shrinked by applying heat. At this time, according to the method of applying heat is divided into wet shrink packaging method and dry shrink packaging method. The heated package is then cooled and a label is placed on the surface of the meat pack to indicate producer or quality.

The food packaging shrinkage machine using the dry shrink packaging method of such shrink packaging is the Republic of Korea Utility Model Publication No. 20-385167 and Republic of Korea Patent Publication No. 10-2011-0073679.

The dry shrink packaging method is such that the heat is blown with a blower on the surface of the film on which the article is packaged to shrink. The shrinkage of the dry shrink packaging method has a problem that the packaging is not properly made while heat is not evenly transmitted to the entire surface of the heat shrink film that packs the article.

On the other hand, the wet shrink packaging method is a method of applying heat to the packaging film using hot water, not hot air, it is possible to transfer heat evenly to the entire surface of the heat shrink film, it is possible to package the food perfectly.

An example of such a wet shrink packaging method is a "heat shrink packaging machine" disclosed in Korean Patent Registration No. 10-658054. The heat shrink wrapper of this technology is hung on two sprockets on both left and right sides so that the lower part is circularly arced, and the upper chain is struck down, and the lower chain is hung on two sprockets on both sides at the bottom of the upper chain. By using, the heat-shrink film packed with the package is configured to heat-shrink in hot water of the heating section and then transferred to the cooling section. That is, in the conventional heat shrink packaging machine, when the sprocket is rotated by the driving unit and a packaged object is inserted between the upper chain and the lower chain, the hot shrinkage package passes through the hot water of the heating unit while being sandwiched between the upper chain and the lower chain. It is locked to the extent that the heat shrink film is heat shrinked and then transferred to the cooling unit.

As described above, the conventional heat shrink packaging machine passes through a heating unit in which hot water is stored in a state where the packaged object is sandwiched between the upper chain and the lower chain by the weight of the upper chain. By the way, the packaged material is a cow, a pig or a chicken, etc., and its variety, size and weight vary. Therefore, in the case of a package of a size or weight that can pass through the heating part smoothly while being sandwiched between the upper chain and the lower chain by the weight of the upper chain, smooth transfer to the cooling part is possible through the heating part. However, in the case of a package of a size or weight that is not the same, a phenomenon in which the upper chain and the lower chain are not transported and is lost in place occurs. That is, the packaged object is not transported after being heated in the hot water of the heating unit for a predetermined time, and as the package is continuously heated in place, there is a problem that the packaged product is ripened by the hot water and loses its value as a product. For example, if a large package is introduced first, followed by a small package, the small package cannot be pressed by the upper chain as the upper chain is lifted by the large package. The above problems occur.

In addition, the conventional wet shrink packaging machine is a component such as a conveying conveyor in the cooling tank of the shrinkage is fixed, there is a problem that disassembly and assembly between each component is not easy. Therefore, if the packaged food falls into the bottom surface of the cooling tank or other objects fall into the bottom surface of the cooling tank during the transfer by the conveying conveyor, it is difficult to remove it. In addition, there is a problem that the cooling tank is unsanitary because it is not easy to clean the parts of the worker's hand, such as the lower portion of the transfer conveyor. In addition, as the conveying conveyor is configured to have only an inclined upward structure from one side of the cooling tank to the other side, there was a disadvantage that the cooling time of the packaged food is short.
