摘要： PURPOSE: To perform a collision jet cooling of a favorable heat conductivity by a method wherein a first temperature zone which introduces a food in a tunnel is set to be a non-freezing temperature zone of a specified temperature range, and after removing steam being vaporized in the non-freezing temperature zone as liquid drops, the food is made to enter a freezing temperature zone. CONSTITUTION: A tunnel type refrigerator 31 in which a net conveyor 14 to transfer a food in the direction shown by arrow is provided is divided into 3 zones, and the first temperature zone 10 is set to be a non-freezing temperature zone of a temperature range of approx. 0-5 deg.C. In the non-freezing temperature zone, vaporized steam is removed as liquid drops, and by the removal, an unnecessary steam of the food is removed at the non-freezing temperature zone. Then, in a zone 11 where a high speed cool gas is blown to the food, the food is rapidly frozen while preventing a dripping from generating, and in a zone 12 for cold-keeping, the food is stored under a frozen state. By this method, a collision jet type cooling of a favorable heat conductivity can be performed without relying upon a plate fin type heat-exchanger.

摘要： PURPOSE: To improve the energy efficiency of the installation by making it possible to separate only air from NH3 vapor evaporated during the fabric processing step and efficiently recovering ammonia from the NH3 vapor. CONSTITUTION: In the process treating cloth with ammonia using an absorption column 3 for cooling and liquefying the NH3 vapor formed in the cloth treatment and an air purger for separating the air from the NH3 vapor, the NH3 liquefied in the absorption column is fractionated into the high concentration NH3 vapor and the low-concentration NH3 solution through a rectification column. The high-concentration NH3 vapor is compressed, condensed and used in the cloth treatment while the low-concentration NH3 solution is used as an absorbent in the absorption column whereby the vaporized NH3 is perfectly recovered.

摘要： PURPOSE:To prevent hunting of an expansion valve opening control system by simple method in a system for cooling matter to be cooled by evaporating refrigerant reduced under pressure by an expansion valve in a cooler. CONSTITUTION:Nonlinearity of a cooler is replaced with a linear control having a gain proportional to a product of a reciprocal of a temperature difference (DELTAt=tr-tg) of a cooler inlet temperature (tr) of matter to be cooled and refrigerant gas temperature (g) by an operation amount (v) calculated by linear control calculation to calculate an operation amount of an expansion valve. When the difference (DELTAt) is small, an increased amount of the preset operation amount is added to present operation amount to increase an opening of the valve.

摘要： PURPOSE:To promote high speed and large capacity easily while reducing an outer diameter by making a circumscribed rotator into rotation and revolution by means of an eccentric turning shaft in a state that an inscribed trochoidal body is locked, and simultaneously rotating a side cover. CONSTITUTION:In an inscribingly fixed trochoidal body 1, a trochoidal tooth form is supported by a cylindrical frame. In addition, an circumscribed rotator 2 with an outer circumferential tooth form generated by this tooth form is installed in an inner space of the trochoidal body 1 rotatably and revolbably via an eccentric turning shaft 4. Further a pair of sliding turntables 5 and 6 are installed at both sides of a pair of fitting gears 1 and 2 consisting of the trochoidal body 1 and the circumscribed rotator 2 and then locked to a tuning shaft 4b. On the other hand, an inlet port and a discharge port are formed in the paired sliding turntables 5 and 6. In succession, a suction pipe 23 and a discharge pipe 24 are connected to a suction chamber 21 and a discharge chamber 22 surrounded by both the sliding turntables 5, 6, a pair of side covers 27, 28 and a frame 29.

摘要： PURPOSE:To enable producing foam containing residuum of organic and inorganic solids in sludge which can be burnt into ash by forming in a foaming vessel a multiplicity of bodies of foam containing scum and solid residuum in a setup to feed the resulting foam to a combustion chamber. CONSTITUTION:An agitating mill 3 grinds with agitation a mixture of foul water which is composed of scum X1 and solid residuum X2 taken out from a primary storage tank 1 and foul water X3 containing floating residuum which had been in the primary storage tank 1 and has been transferred to a secondary storage tank 2 for storage and is added to the scum X1 and solid residuum X2 as they are fed to the agitating mill 3. In the agitating mill 3 a surface-active agent and a neutralizing agent are added to the mixture of foul water, which is next carried by a conveyance line P5, including a pump 5 and piping, and fed to a foaming vessel 6. Foaming takes place in this foaming vessel 6 by feeding of compressed air to the scum, etc., therein. The foam conveyed toward the chamber by a foams-conveyance line 8 is drawn out from an opening by suction toward the incineration chamber 10, inside which the finely divided liquid waste fed in a jet is exposed to a flame of gas injected from a gas burner.
