A heating profile of a microwave oven is modified using microwaves at a plurality of frequencies. A power of transmission to a cavity of the microwave oven of microwaves is defined at each of the plurality of frequencies. A duration is defined for which the microwaves are transmitted at each of the plurality of frequencies. For each of the plurality of frequencies, a proportion of power input to the cavity that is not output from the cavity is measured. The measured proportions am used to modify the power of transmission at each frequency, the duration of transmission at each frequency or both.

A food material powder supply device 1 of the disclosure includes a supply tank 50 that temporarily stores food material powder in a tank 50A and supplies the food material powder to a processing container 2A of a food processing machine 2, a vacuum device 70 that reduces the pressure inside the supply tank 50 with vacuum pumps 71A and 71B, and a control device 3 that operates the vacuum device 70 to reduce the internal pressure of the supply tank 50 to be equal to or lower than a predetermined atmospheric pressure at which moisture of the food material powder is evaporated and cools the food material powder in the supply tank 50. A stirring member 54 which is driven to rotate during the cooling of the food material powder is arranged inside the tank 50A.

A method of freezing juice includes dispensing a predefined amount of the juice into a container, contacting at least one surface of the container with a mass of cooling agent, having a temperature below 78 C., to cool the juice to a cooled juice temperature between 68 C. and 78 C. The container is configured to, in a first cooling stage, allow heat transfer from the juice to the cooling agent to reduce the temperature of the juice to 0 C. at a rate of between 1 C. and 2 C. per minute, and in a second cooling stage following the first cooling stage, allow heat transfer from the juice to the cooling agent to reduce the temperature of the juice to the cooled juice temperature, at a rate of between 1 C. and 2 C. per minute. The temperature of the juice is then maintained between 68 C. and 86 C.

The present invention relates to a system and method for providing a filter to prevent contamination of vacuum pumps during use with freeze dryers. The system and method comprising of a vacuum pump connected to a freeze dryer, the vacuum pump evacuating pressure from the freeze dryer; the vacuum pump connected to a coalescing filter at least partially collects water vapor and the particulate gas, whereby the particulates in the particulate gas are at least partially separated from the gas, the coalescing filter further separating the oil from the water and particulates, whereby the oil is rejuvenated for use with the oil composition; an oil control valve to control pressure in the system and maintain a level of oil in the vacuum pump; a drain valve to enable draining of impurities, and a final filter that injects air into oil exchanged between the sedimentary filter and vacuum pump.

A system for managing spoilage of perishable goods including: a storage device to store perishable good requirements, spoilage characteristics, and perishable good parameters associated with the perishable goods; and a spoilage management system coupled to the storage device. The spoilage management system including: a quality assessment module to determine quality levels in response to at least one of the perishable good parameters and the perishable good requirements; a spoilage determination module to determine spoilage risk levels in response to at least one of the perishable good parameters, the spoilage characteristics, and the quality levels; and a meshing module to determine output parameters in response to at least one of the quality levels and the spoilage risk levels.

The insulated container having an internal support to separate ice, food, and drinks from melted ice water or liquids to prevent damage to the dry items. The dry items are placed on top of the flat upper surface of the removable support. The removable support may include apertures that allow melting ice water to drain past the top surface and through the apertures of the removable support.

A defrosting apparatus has a foundation unit having a top surface and sidewalls, a water pump, an opening enabling water to pass into the unit, a vertically-oriented conduit extending from the top surface and connected to the water pump, and an upper end, a horizontally-oriented conduit having a first and a second end, connected to the upper end of the vertically-oriented conduit, and a downspout connected at the second end of the horizontally-oriented, conduit, the downspout open at a lower end. Water from outside the foundation unit passes through the opening, is drawn into the inlet of the pump, passed from the outlet of the pump to the lower end of the vertically-oriented conduit, passes upward to the horizontally-oriented telescoping conduit assembly, and thence to the downspout, where the water flows down to be collected outside the foundation unit, available to pass again into the foundation unit through the opening.

The invention proposes a device (1) for controlling the temperature of products to be frozen during a freeze drying process. This device (1) is characterized in that at least one Peltier element (3) is present.
