A method for controlling the temperature of edible dough to efficiently and promptly control the dough temperature without adversely affecting the working environments, to operate them for a long period of time, and to apply them to any type of a mixer. The method for controlling the temperature of the edible dough during a kneading step includes a step of kneading the edible dough. During the kneading of the edible dough, the method includes a step of introducing a predetermined amount of gas having a predetermined temperature and a predetermined humidity into a mixer. It is preferable that the gas for controlling the temperature of the edible dough has been prepared and kept in advance at a predetermined temperature and humidity, and is then introduced into the mixer on demand. It is also preferable that the gas is circulated and re-used without being discharged out of a system in which the mixer operates.

A method for separating and recovering an objective component from a crude liquid by a membrane in a semi-batch system, including the steps of: at least two stages of adding a washing liquid to the crude liquid stored in a container and mixing the washing liquid with the crude liquid to form a mixture of the crude liquid and the washing liquid, wherein successive ones of the at least two stages are separated by a time lag, wherein the successive ones use washing liquids at different concentrations, in descending order, of the objective component concentration, and further wherein a last one of the plural stages uses only a washing liquid having essentially a zero concentration of the objective component; and for each of the plural stages, performing a step of membrane treatment of the mixture to transfer the objective component from the crude liquid to a permeated liquid.
