Abstract

655,061. Freezing fish etc.; cold accumulators. BARRIS, P. G. M. Jan. 23, 1948, Nos. 2146 and 2147. Convention dates, Feb. 10, 1947, and May 30, 1947. [Class 29] [Also in Group VI] Foodstuff such as fish, meat, fruit or vegetables is preserved and frozen by coating it with an airtight layer of small pellets of very cold ice, frozen syrup or frozen brine formed, e.g. by the apparatus described in Specification 655,060, the layer being such as to bring the foodstuff to the required low temperature without any other source of cold. A stationary drum 1 having charging and discharging ports 3, 7 closed by doors 5, 6 and 9, 10 respectively contains a rotating drum 2 divided into sectors 14, 14<SP>1</SP>, 14<SP>2</SP>.... Each sector has a slot 15 leading into the hub of the drum 2, this hub containing a distributer 12 for the pellets having half as many slots 13 as there are slots 15. The pellets are positively charged by a source of electric potential on arriving at the distributer and the foodstuff is negatively charged in the' charging port 3 and in alternate sectors 14<SP>1</SP>, 14<SP>3</SP> .... In positions 14, 14<SP>2</SP> ... pellets can enter the sectors, and because of the charges form a coating round the foodstuff. Alternatively, gravitational or centrifugal means may be used to deposit the pellets. It is stated that by forming the pellets of a certain size the size of the crystals in the frozen foodstuff may be controlled. The Specification as open to inspection under Sect. 91 states that, before coating, the foodstuff may be dusted with flour to increase adhesion of the coating. This subject-matter does not appear in the Specification as accepted.
