An ultrasonic freezing equipment, which includes a casing, a circulating pump system, an ultrasonic generator, a vortex-tube freezing device and a temperature-measuring device. A vertex tube is configured for refrigeration. A circulating salt solution inside the casing is configured to quickly and uniformly take away a heat of a food to be frozen, so as to efficiently freeze the food. A freezing method using the ultrasonic freezing equipment is also provided.

An apparatus for disinfecting products is disclosed herein. The apparatus comprises a tank for holding a liquid for receiving microorganisms from the products. The tank comprises a barrier separating the tank to provide two regions of liquid, the two regions of liquid comprising a first region and a second region, wherein the first region is arranged to provide an open channel for the liquid through the tank to enable a product to be carried into, along, and out of a flowpath through the channel; and the second region holds liquid adjacent to at least one ultrasonic transducer for providing ultrasonic energy to the product via the liquid in the second region and through the barrier.

Methods for treating poultry during processing for increasing the weight of the poultry are disclosed. The methods may be performed in a chill tank or other reservoir and utilize either equilibrium peracetic acid or non-equilibrium peracetic acid. The non-equilibrium peracetic acid may be prepared from hydrogen peroxide and a liquid acetyl precursor, such as triacetin. The methods comprise contacting a poultry carcass with peracetic acid-containing water at a pH of about 6 to about 9. The methods result in an increase in the weight of the processed products and an increase in a processing plant's percent yield of the processed products.

Embodiments of the present disclosure provide an auger dip apparatus for the application of antimicrobial solution to raw food. Embodiments of the present disclosure may use an auger as a single moving part to move the food work pieces through the application area for antimicrobial solution. Embodiments of the present disclosure are simple with only one moving auger part to move the food pieces, and the bearing for the moving part, supporting the shaft of the auger, may be configured to be outside of the cabinet with the reservoir of the antimicrobial solution, so that the bearing is not in contact with the antimicrobial solution. This provides for less maintenance and downtime, particularly unscheduled downtime, than a system using more complicated exposed parts. The present disclosure also permits a more compact and lighter configuration for an assembled application unit.

A marinator apparatus for the preparation of pieces of a whole chicken includes a fluid-tight hollow drum with opposing top and bottom walls that are substantially planar and that include an opening with a lid configured to sealingly close the opening. The drum further includes an interior baffle fixed inside that separates the drum into a top compartment accessible only through the top opening and an opposite bottom compartment accessible only through the bottom opening. The drum is supported for rotation by a support axle projecting from one end wall and a drive axle projecting from the opposite end wall. The drive axle includes a driven gear configure to be driven by a powered drive gear.
