What is the working principle of yoghurt machine?
Yogurt machine is divided into: civil series, industrial series. Civil series is divided into: home type, and commercial type two. Regardless of that series of yogurt machine, its manufacturing principle should meet the requirements of modern yogurt processing technology, that is, according to the different strains of fermented yogurt, yogurt function provides different fermentation parameters.
In fact, if you want to do it yourself, you don't need yogurt machine at all,Method:1. buy 2 cup sour milk as strain, 2 cup sour milk can be inoculated 1 cases pure milk. Pure milk is through anti-virus, but the sugar anti-virus, heating to more than 90 degrees, put the sugar in, heat preservation for about 10 minutes2., use the empty bottle boiling disinfection, cold after use.3., the milk will be heated to 90-95 degrees, 20 minutes, in boiling with 5% to 6% of sugar, the boiling sterilization of milk, cold to 40-43 degrees C inoculation.4., buy the sour milk into the cooling to about 40 degrees in the milk, and stir, and then loaded into the poison bottle, it can be a glass bottle, boil it, the lid is also anti-virus,
Household yogurt machine is different. In order to minimize the difficulty of the operation of consumers, as much as possible to simplify the operation process. Therefore, the requirements of domestic yogurt machine: corresponding to different yogurt fermentation agent, yogurt machine can provide different fermentation parameters, consumers only need to choose. The manufacturing principle of yogurt machine must be strictly in accordance with the orderly design of lactic acid bacteria growth and reproduction, physiology of symbiosis, symbiosis provides optimum fermentation parameters for lactic acid bacteria, different temperature conditions, to ensure the growth of lactic acid bacteria in the process of individual cell division and reproduction needs, meet the nutritional conditions of inoculation temperature incubation period. Over temperature conditions of temperature bacteria symbiosis balance and culture activity of stable generation of logarithmic phase.Therefore, home yogurt machine should not be a simple insulation or thermostat, according to the special use of yogurt fermentation agent, reasonable design fermentation parameters and functional control.
Because of its high complexity, the industrial yogurt machine can control the links and parameters more, and ferment parameters are changed according to the different strains of lactic acid bacteria and the proportion of lactic acid bacteria in the yoghurt ferment.
