It relates to a livestock feed mixing device that can reduce the feed cost by increasing the.

In general, the blended feed used in livestock farms has the purpose of uniformly supplying nutrients suitable for the purpose of breeding livestock to maintain the health of the livestock and exert sufficient production capacity. The use of blended feeds can eliminate the effects of livestock disease and improve the quality of the meat by allowing you to consume a lot of nutrients. Formulated feeds have many benefits in terms of livestock farming than using normal feed, but the relatively expensive price is a problem. From an economic point of view, even if a blended feed having the same nutritional value is different depending on the type of raw material to be blended, it should be possible to produce the blended feed at a low price if possible.

There are many types of each unit feed of compounded feed. In general, grain feed includes corn, sorghum, wheat, barley, soft wheat, and rye, and wheat bran, rice bran, rice bran, soybean meal, starch meal, etc. have. In addition, there are various types of unit feeds such as oil-based feed, vegetable protein feed, animal protein feed, and supplement feed. Since the nutrient content of each unit feed is all wrong, the selection and proper mixing of the unit feed can be directly related to the reduction of feed cost.

In the related industry, various mechanical devices have been developed to prepare optimal blended feeds by mixing each unit feed. The recently developed and commercially available fully mixed feed blender (TMR) in the related industry is a mechanical device that feeds irradiated and rich feed mechanically after compounding based on the blending ratio program. In the related market, the demand for TMR feed, which is economical and can increase feed value by using various agricultural by-products as a raw material, has emerged, and the demand from cows to beef cattle is spreading. Accordingly, in the reality that the types of blenders are diversified and the technology is evolving, we are facing the challenge of increasing the market share by manufacturing and supplying products with various performances suitable for the working environment and conditions of individual farms.

In the TMR specification management, it is very important to mix well and thick feeds. In the process of mixing feed and thick feeds, it adds a steam function and a heating function to increase the viscosity of the feed, so it can appeal to consumers by providing feed cost savings. It is absolutely necessary to upgrade to an existing product.

According to the present invention, in the fully mixed feed mixer (Total Mnixed Ratio; TMR), livestock feeds were adopted by combining a primary heating method by hot air and a secondary heating method by steam.

The direct heating method by hot air is a method generally employed in TMR, but in the present invention, in addition to the primary heating by hot air, secondary heating using steam generated when circulating the heat medium oil is additionally adopted.

As the purpose of sterilization and sterilization, indirect heating is a heating method that is widely used for industrial purposes beyond direct heating, in which steam is brought into direct contact with the object to be heated. Indirect heating is a heating method using a heat exchanger or the like, and the heating method using such a heat exchanger is not limited to steam and is performed even when other heat mediums such as hot water or oil are used.

The heating by steam converts the steam supplied to the heat exchanger in a gaseous state into a liquid state (condensed water) and discharges it to the heat exchanger. At this time, the heat of the steam is transferred to the object to be heated through the wall surface of the heat exchanger, and thus the steam and the object to be heated Water is not in direct contact. Steam when viewed as a heating medium has excellent characteristics that other heating mediums do not have. Among them, a typical characteristic is that uniform heating is possible and rapid heating is possible.

When the vapor condenses and returns to the liquid, it releases the latent heat it retains. When the amount of latent heat released is compared with the amount of sensible heat of hot water after condensation, it is about 2 to 5 times, and this heat is released in a moment to pass to the object to be heated through a heat exchanger. Since condensation heat by steam can be significantly larger than convection heat by hot water or oil, steam heating can shorten the heating time, and has the advantage of designing a small heat transfer area.
