5results about How to "Avoid product quality degradation" patented technology

The present application relates to the technical field of feed processing, and particularly relates to a preparation method of Maotai-flavor distiller's grains fermented feed, which comprises the following steps: drying treatment based on the moisture content of Maotai-flavor distiller's grains to obtain basic distiller's grains; determining the strain ratio of brewer's yeast, bacillus subtilis and aspergillus niger based on the tannin content of the basic distiller's grains to obtain a compound fermentation inoculant; inoculating and then fermenting; determining state evaluation parameters based on the total polyphenol accumulation rate, the dissolved oxygen consumption rate and the microbial activity index during the fermentation process, and performing qualified evaluation, and dynamically adjusting when unqualified; determining the fermentation end point based on the tannin degradation rate and the total polyphenol accumulation rate; and mixing the fermented distiller's grains with the basic feed at a mass ratio of 1% after low-temperature drying of the fermented distiller's grains. The present application realizes three-layer control of raw material evaluation, process control and end point determination, significantly improves the stability and content of functional active ingredients in the product, reduces the tannin and safety risk, and has a good intestinal health improvement effect on animals.

The utility model relates to the technical field of injection molds, in particular to an automobile part injection mold, which comprises a female mold body and a male mold body matched with the female mold body, a female mold cavity is arranged in the middle of the female mold body, a female mold matching surface is arranged in the middle of the female mold cavity, an edge tearing groove is arranged outside the female mold cavity, and a plurality of flash grooves are uniformly arranged outside the edge tearing groove. A first hot runner injection port is formed in the middle of the female mold body, a second hot runner injection port is formed in the middle of the male mold body, a female mold cooling runner is formed in the female mold body, a male mold cavity is formed in the middle of the male mold body, and a male mold matching surface is formed in the male mold cavity. Compared with the prior art, the material head is effectively prevented from being generated, the material head does not need to be cut, multi-point uniform injection of material liquid is achieved through the multiple hot runner material injection openings, the uniformity in the injection molding production process is improved, and the problem that the product quality is reduced due to material overflowing is solved through the arrangement of the edge tearing groove and the material overflowing groove.

This invention discloses a homogenizing device for fragrance production, relating to the field of specialized machinery for fragrance processing. The homogenizing device includes a homogenizing tank, a support plate fixed to the bottom of the tank, a motor fixed to the side wall of the tank, a rotating rod fixed to the output end of the motor, a stirring spiral ring fixed to the outer wall of the rotating rod, and a connecting block penetrating the top of the tank. When the temperature inside the homogenizing tank reaches the critical volatilization temperature of the volatile components in the fragrance, this homogenizing device can actively cool the copper plate by incorporating a semiconductor cooling chip, a temperature sensor, copper pipes, a control panel, and a copper plate. Since the copper plate is fixed inside the homogenizing tank, its cooling effect can be directly transferred to the tank and the fragrance materials inside, thereby achieving an overall cooling effect on the homogenizing tank and effectively preventing the loss of aroma components due to high temperature volatilization, thus avoiding a decline in product quality.

The utility model discloses a glass steel -toughening furnace with preheating mechanism belongs to glass steel -toughening furnace technical field, including the toughening furnace main part, the feed inlet position department of toughening furnace main part is installed with the feeding pedestal, the upper surface fixed mounting of feeding pedestal is installed with the mounting bracket, be provided with two mounting plates between feeding pedestal and mounting bracket, two the mounting plate is below one after another opposite layout, the opposite face of two mounting plate all fixed mounting has preheating heating plate, the mounting plate fixed mounting in the inner wall of feeding pedestal in lower position, through setting two preheating heating plates of up and down cooperation feeding pedestal uses, can realize preheating heating before material enters to the inside of toughening furnace main part, promotes material initial temperature, effectively prevents the phenomenon of the rupture of high temperature that meets and is directly sent into the inside of toughening furnace main part, and the preheating heating plate of upper side can carry out the adjustment on height, is suitable for different thickness material preheating heating use.
