Fish soluble concentration device

Abstract

The invention discloses a fish soluble concentration device, which relates to the technical field of fish soluble preparation. The device comprises a reaction tank for concentration and a condenser for steam liquefaction, wherein a liquid storage box body of which the upper end is a plane and in which liquid is used for heat conduction is mounted on the peripheral side surface of the lower half part of the reaction tank; a through hole is formed in the lower end of the liquid storage box; an oil bath electric heater is welded and fixed at the edge of the through hole; steam generators which are symmetrically arranged relative to the axis of the reaction tank are mounted in the liquid storage box body; and the two ends of the steam generator penetrate through the upper side of the liquid storage box. A liquid storage box body and an oil bath electric heater are mounted at the lower part of the reaction tank for heating so as to conduct heat to the whole reaction tank, a steam generator provides steam and hot air to the interior of the lower end of the reaction tank, and the interior and exterior of fish soluble in the reaction tank are simultaneously heated and are matched with a crushing stirring disc, a separating and mixing stirring disc and a scraping disc for stirring and scraping; the concentration process of the fish soluble in the reaction tank is uniform, and the steam condensed and discharged by the external condenser accelerates the discharge efficiency and accelerates the concentration efficiency.

Description

technical field [0001] The invention belongs to the technical field of fish soluble pulp production, and in particular relates to a fish soluble pulp thickening device. Background technique [0002] Fish pulp is the press wastewater produced during the fishmeal production process, and every ton of fishmeal produced produces two to three times as much fish pulp. In the previous fishmeal production process, fish lysate was usually discharged directly into the environment, which not only wasted this protein-rich resource, but also caused serious environmental pollution. In recent years, researchers in the industry have done a lot of research on how to use fish soluble pulp, such as using fish soluble pulp to produce food-grade umami flavor (CN107136465A), the obtained umami flavor agent is easy to absorb and has a good flavor, or using fish soluble pulp The preparation of protein fertilizer (CN105060944A) not only provides nutrients to crops and increases production, but also ...
