This invention relates to the field of liquid-liquid separation and discloses an apparatus and method for aromatic hydrocarbon extraction. The apparatus includes a raw material tank, a solvent tank, a mixer, and an extraction tower. The raw material tank is connected to the raw material inlet of the extraction tower, and the solvent tank is connected to the solvent inlet of the extraction tower. The mixer includes a spray section and a mixing and extraction section. In the mixing and extraction section, the raw material and solvent are broken and diffused through multiple variable diameter sections and rotated by a single helical blade. Finally, the mixing is completed in a petal-shaped turbulent mixing chamber, which effectively improves the mixing and emulsification effect of the raw material and solvent, which is beneficial to improving the extraction efficiency. The apparatus has a compact structure and low energy consumption, and is particularly suitable for aromatic hydrocarbon extraction in the fields of chemical, food, coating, and cosmetic industries.

The utility model provides a food coating production line, and relates to the technical field of food coating, the food coating production line comprises a coating production line, a first electric sliding rail is arranged above the coating production line, and a first electric sliding block is slidably mounted on the outer side of the first electric sliding rail. A raw material conveying pipeline is connected with a coating raw material storage tank, raw materials can be conveyed through a pump machine and enter the inner side of a coating raw material storage cavity, at the moment, a first electric sliding block can be controlled to slide above a first electric sliding rail, and after the first electric sliding block slides, a transmission gear above the first electric sliding block can be meshed with a rack; the transmission gear can drive the rotating shaft and the finger biscuit coating covering roller to rotate, finger biscuits in the finger biscuit coating covering roller can make uniform contact with raw materials, food rolls in the finger biscuit coating covering roller, and it is ensured that coatings evenly cover all the surfaces of the food.

This invention relates to the field of food coating materials technology, providing an environmentally friendly two-phase shellac coating agent and its application in promoting flavor release. The coating agent is an oil-in-water emulsion. The aqueous phase contains modified shellac salt, a glycerol-sorbitol complex, and an octenyl succinate-sodium starch-cellulose nanocrystal complex; the oil phase contains a hydrophobic shellac resin, medium-chain triglycerides, and an electrostatic complex of chitosan and carboxymethyl-β-cyclodextrin. An interfacial functional layer is constructed through hydrogen bonding and multiple interactions, achieving a smart response of high barrier properties during storage and rapid release upon wetting. This invention is entirely aqueous, contains no organic solvents, has an elongation at break of 235%, a flavor release rate of 82%, and also possesses antibacterial properties. It can be used for the preservation and flavor control of fruits, vegetables, nuts, and other foods.

This utility model relates to the technical field of food coating devices, solving the technical problem of the need for periodic sieving of flour. Specifically, it relates to a food seasoning coating device, comprising a support frame as a supporting base, a coating sieving component for coating food ingredients on the support frame, and a flour circulation component for recycling the sieved flour in conjunction with the coating sieving component. The coating sieving component includes a coating fixing frame fixedly connected to the support frame, with two symmetrical stabilizing grooves on both sides of the coating fixing frame. Due to the inclusion of the coating sieving component, this utility model enables sieving-type coating of food and filters out dough impurities generated during the process. Utilizing the power generated during the sieving coating process, it improves processing efficiency while reducing production costs.
