Problems solved by technology

During the whole preparation process, constant solution heating equipment is needed, and the culture medium needs a high-temperature heating link before moist heat sterilization. On the one hand, the investment in equipment is increased, space is occupied, and production costs are increased. On the other hand, the high-temperature heating link increases Chance of excessive degradation of nutrients, resulting in loss of nutrients

Abstract

The invention discloses a culture medium cold-filling preparation process. The preparation process includes following steps: weighing solid or liquid components of reagents needed for culture medium, dissolving and mixing the weighed culture medium components, adding pure water 30%-50% of the volume into a filling machine, adding the dissolved culture medium components while stirring, subjecting the culture medium mixture to constant dissolving, adjusting PH (potential of hydrogen) value, adjusting the rotation speed of the filling machine to be 150-270r / min for stirring, adjusting the pneumatic pressure of the filling machine to be 0.01-0.02MPa, filling at the normal temperature, and covering and sealing the filled culture medium for steam moist heat sterilization. Preparation of the culture medium can be completed only by weighing instrument equipment and packaging sterilization equipment without constant-dissolving and heating equipment, so that preparation time of the culture medium is shortened, production efficiency is improved, production cost is lowered, energy is saved and emission is reduced, excessive degradation of nutritional components is avoided, and various nutritional components of the culture medium are protected from being damaged.

Description

technical field [0001] The invention relates to a preparation process of a medium, in particular to a preparation process of a medium cold filling. Background technique [0002] At present, there are many kinds of medium, which are widely used in various technical fields such as biotechnology. The traditional medium preparation process usually adopts the following steps: Weighing the components of the medium, fully dissolving and mixing the components of the medium, and then heating to Stir while heating at a certain temperature to fully dissolve and mix the ingredients. After cooling, adjust the pH value to the specified value range, and then fill it. Cover the filled culture medium with a sealing film and then carry out steam damp heat sterilization. During the whole preparation process, constant solution heating equipment is needed, and the culture medium needs a high-temperature heating link before moist heat sterilization. On the one hand, the investment in equipment is...
