US Patent:

8196423, Jun 12, 2012

Filed:

May 22, 2009

Appl. No.:

12/454741

Inventors:

Kyle B. Elsom - Batavia IL, US
Vincenzo DiFatta - Wood Dale IL, US
Christopher Knight - Lisle IL, US

Assignee:

IMI Cornelius Inc. - Glendale Heights IL

International Classification:

A23G 9/00

US Classification:

62342, 62346

Abstract:

A recovery system for a frozen product dispenser accommodates automatic recovery and continued operation of the dispenser in response to the output torque of a beater bar and scraper assembly drive motor exceeding a selected upper limit due to transient conditions. A controller monitors the output torque of the drive motor and, upon sensing an output torque in excess of the selected upper limit, shuts off the drive motor and operates a refrigeration system to defrost a freeze barrel within which the beater bar and scraper assembly is rotated, for a time sufficient to defrost product in the barrel. The controller then turns on the drive motor, operates the refrigeration system to refreeze product in the barrel and continues to monitor the output torque of the drive motor. The foregoing operation is repeated several times, if and as necessary, before a system error is generated.

International Classification:

US Classification:

622283, 62129, 622281

Abstract:

A method and system for detecting and correcting unintended reverse or backward operation of an electric motor driven scroll compressor of a refrigeration system is characterized by monitoring the pressure at a suction side of the compressor during operation of the refrigeration and determining whether the pressure, after a first time interval following startup of the compressor, exceeds and remains in excess of a predetermined upper pressure limit for at least a second time interval. If it does, the compressor is turned off for a third time interval and is then restarted. The foregoing is repeated and if the compressor is turned off a selected number of times because of successive occurrences of high suction side pressures during operation of the refrigeration system in a chilling cycle, an error indication is generated and the refrigeration system is shut down.

Abstract:

Apparatuses, systems, and methods are for dispensing condiments, including a base condiment together with and at least one additive. In some examples, a dispenser apparatus comprises a dispenser body having an upstream inlet that is configured to receive the base condiment and a downstream outlet that is configured to dispense the base condiment together with the additive(s). An additive body is configured to supply the additive(s) into the dispenser body as the base condiment is conveyed from the upstream inlet to the downstream outlet so that the base condiment and the additive(s) are concurrently dispensed via the downstream outlet. The systems and methods can operatively include arrangements for selecting a base condiment; selecting one or more additives from a plurality of additives; and supplying the base condiment and the additive(s) to a dispenser apparatus that dispenses the base condiment and additive(s) together.
