Abstract: PURPOSE: To provide both a method for air conditioning of an automatic koji preparing apparatus mainly useful for brewing and a device. CONSTITUTION: In this automatic Koji (maltedrice) preparing apparatus comprising a single or plural Koji culturing beds in a chamber consisting of heat insulating walls, a KOJI temperature ideal with the lapse of time in Koji preparation (hereinafter abbreviated as set Koji temperature) is set in each Koji culture bed. A temperature in the chamber ideal with the lapse of time in Koji preparation (hereinafter abbreviated as a set temperature in the chamber) is set in one point or in each culture bed. In a state in which a measured Koji temperature of each Koji culture bed is higher than a temperature obtained by adding a fixed value (KHn: KH1<KH2<...<KHn<...) to the set Koji temperature, a temperature in the chamber obtained by subtracting a fixed value (RLn: RL1<RL2<...<RLn<...) from the set temperature in the chamber is used as a lower limit.  The temperature in the chamber is dropped until a measured KOJI temperature is lowered to a temperature obtained by adding a fixed value (KHn-1) to the set Koji temperature. In a state in which the measured Koji temperature is lower than a temperature obtained by subtracting a fixed value (KLn: KL1<KL2<...<KLn<...) from the set Koji temperature, a temperature in the chamber obtained by adding a fixed value (RHn: RH1<RH2<...<RHn<...) to the set temperature in the chamber is used as an upper limit. The temperature in chamber is raised until a measured Koji temperature is raised to a temperature obtained by subtracting a given value (KLn-1) from the set Koji temperature.

IPC: F28D11/06
Filed: 1979-12-24
Abstract: PURPOSE: To heat-exchange particles uniformly and effectively by forming on a through a vibration transfer layer of particles in which the particles being vibrated are transferred floatingly and arranging a heat exchanger within the vibration transfer layer so that the heat exchange can be performed by the contact between the vibrated particles and the heat exchanger.  
     CONSTITUTION: A raw material mixed gas fed from a gas inlet 2 is divided by a louver 26 into particles and gas. The separated gas flows to a gas exhaust port 4 to be brought into contact with a heat transmitting pipe 9a through which a cooling medium is circulated. Thus, the gas is cooled. On the other hand, the separated particles sink on the vibrating trough 6 and form a substantially uniform layer due to the vibration of the trough 6, while it is transferred toward the raw material exhaust port. In this while, the particles float up due to the vibration to contact the heat transmitting pipe 9a. Thus, the heat exchange can be performed. According to the heat exchanger of this type, a uniform and effective heat exchange of the particles can be performed by controlling the vibration amplitude and frequency of the trough 6 so that of the vibration transfer layer can have an appropriate thickness in view of the quantity and the moisture containing rate of particles to be treated.

Abstract: PURPOSE:To decrease the fluctuation due to a quantized error by resolving a control voltage into two components, generating a linear voltage component being one of two components of a control voltage from a compensation analog voltage generating circuit and generating a nonlinear voltage component through digital coding, and using the sum as the control voltage. CONSTITUTION:A storage circuit 3 stores in advance a temperature compensa tion digital code to generate a control voltage applying temperature compensa tion to a voltage controlled oscillator 6 and receives a digital code from an A/D converter 2 as its address signal to output a temperature compensation digital code corresponding to a nonlinear voltage component. A compensating analog voltage generating circuit 7 generates the linear component of the control voltage applying temperature compensation to the voltage controlled oscillator 6. An analog voltage V1 outputted from the compensation analog voltage generat ing circuit 7 and an analog voltage V2 outputted from a D/A converter 4 are added at an adder 5 to form a control voltage V3. Since the quantizing error is reduced over a temperature range, the stable frequency temperature character istic with less fluctuation is obtained.
