摘要:
An apparatus is disclosed wherein a highly viscous, heat-sensitive material such as concentrated whole milk or concentrated fruit juice is supplied onto a plural-stage belt conveyor stretched within a vacuum chamber and is dried and solidified by means of a heating member while moving along the belt conveyor. The resulting dried material is received by a fixed cutter provided within a casing disposed at the turning point where the belt conveyor is to turn to the return stroke side. This dried material is then crushed by a crushing device equipped with said fixed cutter and a rotary cutter cooperating therewith, and the thus crushed material is let fall within the casing and discharged to the outside of the vacuum chamber by means of a discharging device equipped with a screw wing installed in the lower part of the casing.

A material feed pipe for use in a belt-system continuous vacuum drier and oriented above a belt moving within a vacuum drying chamber. The feed pipe includes an inner tube having its one end provided with an inlet for material and the other end being closed. An outer tube has its two ends closed and encircling said inner tube with a radial space therebetween. A plurality of nozzle openings are provided in an upper part of the inner tube at a fixed pitch along the axial length thereof. The nozzle openings are so devised as to have a larger diameter in regular succession from the inlet end to the opposite end of the inner tube; and a plurality of further nozzle openings are provided in the lower part of the outer tube at a fixed pitch along the axial length thereof and have a fixed diameter.

A method of producing a cheese product in snack-sized form comprising the steps of cooling a molten cheese to a temperature of about 45.degree. C. to 35.degree. C., heating a surface area extending in the radial direction from the surface of the cheese to a thickness of 1/8 to 1/6 of the cheese diameter of the cooled cheese to a temperature of about 52.degree. C. to 39.degree. C., cutting the heated cheese into snack sized pieces by rolling within a mold die for rounding the pieces of cheese, and forming each of the snack sized pieces into a rounded shape without corners, thereby providing a snack sized cheese product formed into a desirable rounded shape such as spherical, ellipsoidal, and barrel shape and having good appearance without creases and cracks on the surface thereof as well as a homogeneous texture.

An improved new type pyrometer and a method for fusing an alumina pipe having a high purity are disclosed. The temperature-measuring portion of the pyrometer includes a protective pipe made of alumina having a purity of at least 99.9% and a temperature-measuring resistance element of a platinum or platinum-rhodium resistance wire and a holding portion made of alumina having a purity of at least 99.9%. Owing to the use of high purity alumina, the platinum or platinum-rhodium resistance wire is not contaminated and has stable temperature characteristics at high temperatures. According to the method of this invention, an end of an alumina pipe having a purity of at least 99.9% can be fused without the aid of any binder by fusing the end while evacuating air from the alumina pipe through its opposite end.
摘要:
In a subject fluid, there is placed an apparatus for measuring a change in state of the fluid, said apparatus having a tubular body which, in turn, contains therein at least one heating sensor employing so-called hot wire method. A quantity of the fluid is introduced into the tubular body and a temperature of the heating sensor is measured by the heating sensor itself as the quantity of the fluid having been introduced into the tubular body is maintained in a state of laminar flow or a static state. The laminar flow is generated by fluid impeller means such as impeller vane, screw-type vane or propeller vane assembly or uniaxial eccentric pump. The static state is maintained y providing gateway means for passage of the fluid into or out from the tubular body and closing such gateway means. A temperature of the fluid having been introduced into the tubular body and maintained in said laminar or static state is measured and discharged out from the tubular body upon completion of said temperature measurements. A change in state of the fluid is determined based on the temperatures of the fluid and the heating sensor.
摘要:
A sensor comprising a heating element and a temperature detecting element used to measure a temperature of the heating element are both held out of contact with each other within a sensor protecting tube. For fluid exhibiting slow changes in its state as time elapses, a fluid state is measured on the basis of a differential temperature between temperatures prior to and during heating of the heating element. For the fluid exhibiting rapid changes in its state as time elapses, the sensor is caused to generate heat while the temperature of this sensor is measured, and a separate temperature measuring sensor measures the temperature of the fluid. The fluid state is determined on the basis of the differential temperature between the temperatures of the sensor and the temperatures of the fluid.
