Abstract

An apparatus for treating a flowable food product includes a container constructed from a first plastic material; an injection chamber arranged within the container, and including an inlet and an outlet in fluid communication with the injection chamber; at least one nozzle constructed from a second plastic material, the at least one nozzle including a first end in fluid communication with a source of cryogen and a second end in fluid communication with the chamber for providing the cryogen to the chamber. A related system and method are also provided.

First claim

What is claimed is:

1. A system for treating a flowable food product, comprising:
a container constructed from a material selected from the group consisting of TEFLON, plastic, and TEFLON and plastic;
an injection chamber arranged within the container for receiving the flowable food product, the injection chamber including an inlet and an outlet in fluid communication with the injection chamber;
at least one nozzle constructed from a material selected from the group consisting of TEFLON, plastic, and TEFLON and plastic, the at least one nozzle including a first end in fluid communication with a source of cryogen wherein the cryogen is a substance selected from the group consisting of a liquid nitrogen, gaseous nitrogen, liquid carbon dioxide, and gaseous carbon dioxide, each at a temperature in a range of from −20° F. to −321° F., and a second end in direct fluid communication with the injection chamber for providing the cryogen to the flowable food product in the injection chamber; and
a mixer arranged in a pipe section downstream of and separate from the injection chamber, the mixer in fluid communication with the pipe section and the outlet of the injection chamber for providing turbulence to mix the cryogen and the flowable food product.

2. The system of claim 1 , wherein the mixer comprises a shaped member disposed therein to facilitate turbulence of the cryogen and the flowable food product.

3. The system of claim 1 , further comprising a degasser in fluid communication with the mixer for removal of cryogen vapor from said mixer.

4. The system of claim 1 , further comprising:
a first vessel for containing the flowable food product;
a second vessel for containing cool-down flowable food product; and
piping interconnecting the first vessel, the second vessel and the injection chamber of the container for the flowable food product and the cool-down flowable food product to be received in said injection chamber.

5. The system of claim 4 , further comprising a pipe having a first end in fluid communication with a downstream outlet of the mixer, and a second end in fluid communication with the second vessel.

6. The system of claim 5 , further comprising another cryogen delivery apparatus in fluid communication with the second vessel.

7. The system of claim 1 , wherein the material for the container further comprises stainless steel.
