The utility model relates to the technical field of filtering for sucralose decoloration, in particular to a filtering device for sucralose production, which comprises a coarse filtering pipe and a fine filtering pipe which are vertically arranged, the coarse filtering pipe is communicated with the fine filtering pipe through a transverse pipe, and the fine filtering pipe is detachably connected with the transverse pipe. The lower end of the coarse filter pipe is closed, the upper portion of the coarse filter pipe is communicated with a filter screen, the lower end of the fine filter pipe is closed through a baffle, a plurality of water outlet holes are formed in the baffle, filter cloth is laid on the top face of the baffle, and a pressing plate matched with the inner diameter of the suction filter pipe and capable of being arranged above the transverse pipe is arranged above the fine filter pipe. The pressing plate is driven by a driving device to move up and down along the suction filter pipe. By using the sucralose filtering device, the sucralose solution can be secondarily filtered by using the filter screen and the filter cloth, so that the sucralose solution can be prevented from containing carbon powder, and the purity of the sucralose solution is ensured.

This application relates to the technical field of beer production equipment, specifically a dual-channel filtration and filling device for beer production. By installing a pressure mechanism on the filter box, a motor drives a cam to rotate during beer filtration. As the cam rotates, a connecting rod moves a slider up and down within a groove. Simultaneously, the slider moves a sliding rod up and down, achieving intermittent pressure from the pressure plate. This pressure applies pressure to the beer in the filter box located above the filtration mechanism, accelerating the beer's passage through the coarse and fine filters, resulting in faster filtration. Furthermore, by installing a leveling component on the lower side of the filling branch pipe in the filling mechanism, the leveling hood within the component ensures that the beer sprayed through the constriction tube is evenly distributed on the inner wall of the empty bottle during filling after filtration, reducing the impact of the beer on the empty bottle and thus minimizing bubble formation.

The invention discloses a liquid fertilizer production device, and belongs to the technical field of fertilizer production equipment.The liquid fertilizer production device comprises a production box, the upper end of the production box is provided with the production box, the lower end of the production box is fixedly connected with a lower box cover, and one side of the production box is fixedly provided with an air outlet hole; a fermentation barrel is rotationally connected into the production box, a fixing groove is formed in the lower end of the fermentation barrel, and a filter plate is mounted at the lower end in the fermentation barrel; and a driving assembly is installed on one side of the production box, a stirring assembly is installed in the upper box cover, and an automatic defoaming assembly is installed at the lower end in the production box. By designing the automatic defoaming assembly 4, an additional driving source is not needed to provide power for the automatic defoaming assembly, fermented liquid bubbles in the fermentation barrel can float upwards to the liquid level to be broken under the action of buoyancy and hydrodynamic force through shaking, and the filtering flux of the fertilizer is greatly improved.

The utility model discloses a filter high viscosity phosphite's intermediate storage tank, including tank body, the tank body is equipped with feed inlet, gas inlet, vacuum interface, discharge gate and vent, and is controlled by valve independently respectively, stirring paddle is located in the tank body, wherein, gas inlet is used for to the tank body in dry hydrogen chloride gas, to make potassium carbonate convert into potassium chloride and separate out, vacuum interface is used for to discharge the carbon dioxide and water gas of reaction generation. Since in liquid phosphite, the solubility of potassium chloride reduces along with temperature heightening, based on this characteristic, first dry hydrogen chloride gas is passed into the high temperature (>100 DEG C) liquid phosphite containing potassium carbonate catalyst, makes potassium carbonate convert into potassium chloride, because the solubility of potassium chloride reduces under high temperature, will separate out from liquid material, and high temperature can also reduce the viscosity of high viscosity liquid phosphite, double effect realizes the effect of fast filter speed, catalyst removal thoroughly together.

The utility model discloses a resin reflux filter structure, including filter component and support frame, still including filter and filter screen, and support pole main part is main support column, and the connecting ring is set in the upper end of support pole main part, and the connecting structural member is set in the lower extreme of support pole main part, and the connecting structural member is adapted with the tank edge of glue tank, and the connecting ring is used for installing filter component, and the connecting structural member is used for fixed support pole main part, and this kind of resin reflux filter device compares with the simple filter mode of current use, and the operation is simpler, and convenient to replace, saves time, can directly observe the yarn hair content in filter screen, when yarn hair increases and slows down the filtration speed, can stir yarn hair in it and make filtration speed fast, convenient and fast operation, and when not put filter screen, the device can also filter certain yarn hair, has no idle period, prevents when replacing filter screen, and some unfiltered resin will enter glue tank, has higher use flexibility.

The utility model relates to the technical field of milk production, and provides a novel homogenizer for milk production, which comprises a protective shell, the top of the protective shell is provided with a feed inlet, and the bottom of the protective shell is fixedly connected with supporting legs; a stirring device is arranged on the side face of the protective shell and comprises a motor, the motor is fixedly connected to the top of the protective shell, an output shaft of the motor is fixedly connected with a rotating rod, the circumferential face of the rotating rod is fixedly connected with a disc, and the circumferential face of the disc is fixedly connected with a supporting rod. By means of the technical scheme, the problems that in the prior art, the effect that revolution and rotation of the stirring plate are conducted at the same time are difficult to achieve, milk is difficult to evenly mix, it is difficult to guarantee that each part of the stirring plate can make effective contact with materials, substances are difficult to disperse more evenly, and the deposition or caking phenomenon of the materials is increased are solved.

This invention provides a method for extracting and purifying long-chain dicarboxylic acids from fermentation broth, comprising the following steps: 1) Solid-liquid separation: performing a first solid-liquid separation on the long-chain dicarboxylic acid fermentation broth to obtain insoluble matter 1 and filtrate 1; 2) Slurry conditioning and dehydration: conditioning the insoluble matter 1 with a short-chain organic acid and performing a second solid-liquid separation to displace the water in the insoluble matter 1, obtaining insoluble matter 2 and filtrate 2; 3) High-temperature dissolution: dissolving the insoluble matter 2 with a short-chain organic acid at 80-85°C to obtain a solution; 4) Ceramic membrane filtration: filtering the solution through a ceramic membrane at 80-85°C and collecting the permeate; 5) Purification: purifying the permeate to obtain the long-chain dicarboxylic acid product. The method of this invention has advantages such as thorough protein removal, product purity exceeding 98.5%, low total nitrogen content, white color, and fully meeting the requirements of polymerization-grade products.
