Title: Improvements relating to drying chambers
Inventor: ANDERSON HUGH DAVID
IPC: F26B17/10
Filed: 1958-07-24
Abstract: 892,220. Drying systems. BRITISH-AMERICAN TOBACCO CO. Ltd. July 15, 1959 [July 24, 1958], No. 23874/58. Class 34(2) Loose material such as sawdust, woodchips, granular and fibrous materials, is dried in a pneumatic drying system comprising vertically arranged diverging-converging drying chambers 6, 7. The moist material is fed to the hot air stream through a rotary air-lock valve 5 whilst the dried product is discharged from a cyclone separator 8 via a further rotary air-lock valve. The dust-laden air from the separator 8 passes to a cyclone separator 9 from which the cleansed air is withdrawn by a fan 1 for either discharge to atmosphere or recirculation via ducting 3. Each of the chambers 6, 7 is so proportioned that the velocity of air flow may be adjusted such that the flow in the chamber is insufficient to overcome the force of gravity on denser portions of the material, so that such portions will lose their initial upward velocity before reaching the top of the chamber and will sink back in the outer part thereof and execute a circulatory motion therein until their density has lessened. The chambers are also so proportioned relative to the associated ducting of the system that the velocity of flow in the chambers is substantially lower than that obtaining in the rest of the system. If the dried material is to be cooled, the chambers 6, 7 may be followed by one or more chambers having cooling means and of a similar construction to the chambers 6, 7, into which jets of cold air may be introduced to impart a helical motion to the material. The chambers 6, 7 may incorporate jets for the introduction of additional hot air to give the material a helical motion. Specification 875,684 is referred to.

Abstract: 1,197,954. Thawing frozen foods &c. CLARKE-BUILT (WILLIAMS) Ltd. 20 May, 1968 [23 May, 1967], No. 23978/67. Heading A2D. Frozen products are thawed by enclosing in a sealed chamber, removing substantially all the air from the chamber and then admitting steam to establish a predetermined temperature within the chamber and to condense directly on the surface of the product and thaw it. Air is subsequently readmitted and the thawed product and the condensed steam and water draining therefrom are withdrawn from the chamber. With frozen food, such as fish, the chamber is evacuated to about 2 mm. mercury and steam is then admitted until the temperature rises to 8-9‹C., as determined by a wet bulb thermometer, and at which level the temperature is maintained by automatic control of the steam supply to the chamber. A flow diagram illustrates a suitable apparatus in which steam ejectors are used to remove the air and condensate from the chamber.
