This permits light weight packaging with the maintenance of temperatures in narrow, pre-selected ranges over extended periods of time. A nylon and low density polyethylene thermal blanket comprising cells substantially filled with phase change material, which is advantageously puncture proof, durable, and capable of surrounding any payload, is disclosed.

Abstract: An apparatus for a frozen food product, such as an ice cream or frozen-yoghurt product, produces an aerated and flavored base mix. The base mix is provided in a liquid form to the apparatus and is mixed with a gas in the apparatus to aerate the base mix. Flavor is added to the aerated base mix in a turbulence tube of the apparatus, and the aerated and flavored base mix is then deposited out of the turbulence tube onto a cold plate of the apparatus as a thin layer material. The cold plate may be disposed such that it is in open view of a customer. One or more solid-food mix-in additives can be added to the aerated and flavored base mix on the cold plate. The aerated and flavored base mix is allowed to at least partially freeze on the cold plate with the additive(s) dispersed therein to produce a frozen food product, which is then manually scraped from the cold plate and served to a customer.

Abstract: Salt water fed to an ice-maker 1 is cooled to generate ice. The ice is scraped by scrapers 1c to form small particles of ice which are mixed with the salt water to generate salt water-mixed sherbet ice 143. The salt water-mixed sherbet ice is fed from the ice-maker to an ice storage tank 14 so as to be stored in the ice storage tank. A predetermined amount of the salt water-mixed sherbet ice with a predetermined sherbet concentration at a predetermined low temperature is stored in the ice storage tank while the salt water-mixed sherbet ice is refluxed from the ice storage tank to the ice-maker. Water 24 is injected into the salt water-mixed sherbet ice in the process of producing the salt water-mixed sherbet ice. By the method of producing salt water-mixed sherbet ice, salt water-mixed sherbet ice at a relatively high temperature can be produced easily.
