Oyster calcining technological process

Abstract

The invention discloses optimal processing technology for oysters, which comprises the process steps of: (1) crushing the oysters, and placing the crushed oysters into a crucible; (2) selecting the toxicity and drug effect as indicators, and screening the calcination temperature; (3) selecting four investigation factors, namely calcination temperature, calcination time, grinding particle size and matting thickness, taking three levels respectively, and selecting an L18(37) orthogonal table for calcination; (3) determining relative hardness, relative density, porocity and CaCO3 content of the calcined oysters respectively; (4) performing score calculation on the determination result to obtain comprehensive score; and (5) performing variance analysis on the comprehensive score to obtain the preferred processing technology for the oysters, namely the oysters are crushed into small pieces with a particle size of 5cm3 which are paved to a thickness of 4cm and are calcined at a temperature of 550 DEG C for 1.5 hours, and selecting relative hardness, relative density, porocity and CaCO3 content as evaluating indicators. The relative hardness of the obtained calcined oysters is 30.67, the relative density is 3.0, the porocity is 0.86, the CaCO3 content reaches 94.77 percent, and the obtained calcined oysters have good reproducibility and satisfy pharmacopoeia standards.

Description

technical field [0001] The invention relates to an oyster calcining process method in the technical field of traditional Chinese medicine calcining. Background technique [0002] The oyster is the shell of Ostrea gigas Thunberg, Ostrea talienwhanensis Crosse or Ostrea rivularis Gould, which are animals of the Oyster family. The main component of oysters is CaCO 3 , first recorded in "Shen Nong's Materia Medica", listed as top grade, a clam. Salty, slightly cold. Return liver, gallbladder, kidney channel. It has the functions of calming the nerves, suppressing yang and tonifying yin, softening hard masses and resolving stagnation, and is used for palpitation and insomnia, dizziness and tinnitus, scrofula and sputum nucleus, lump in the abdomen. Calcined has the function of astringent and astringent, and is used for spontaneous sweating and night sweats, nocturnal emission and metrorrhagia, stomach pain and acid regurgitation. [0003] The processing methods of oysters ha...

Problems solved by technology

[0005] The purpose of the wood invention is to overcome the disadvantages of oyster calcination process currently on the market that there are no clear regulations on calcination temperature, time, particle size and bedding thickness, so as to provide a unified oyster calcination process and solve the problem of labor-intensive, time-consuming and poor quality in production. Unfavorable and unsuitable for mass production
