Abstract:
An object of this invention is to provide a parboiled rice manufacturing apparatus capable of efficiently manufacturing good-quality parboiled rice without increasing the overall size of the apparatus. A parboiled rice manufacturing apparatus according to this invention includes a drum which has a raw material hatch provided at a peripheral surface and is disposed to be rotatable about a horizontal axis, a heating unit which is disposed inside the drum and heats an interior of the drum, an agitation unit which is disposed inside the drum and agitates a raw material charged through the raw material hatch into the drum, a steam supply unit which supplies steam into the drum, a pressure adjustment unit which has a valve allowing communication of the interior of the drum with outside air and allows increase of pressure inside the drum with steam supplied from the steam supply unit by closing the valve at the time of processing of the raw material through the pressurized steam-boiling treatment, a water addition unit which is disposed inside the drum and adds water to the raw material inside the drum, and a drying unit which dries the raw material by reducing the pressure inside the drum.
Abstract:
A food processing apparatus (20) including a tank (24) having an inlet end (32) for receiving food product and an outlet end (40) for discharging food product, the tank having an inner wall (44) defining a compartment (52) and including a solid, imperforate wall portion (46), fluid being contained in the compartment, and a rotatable auger (88) mounted in the compartment (52), the auger (88) for advancing food product within the compartment (52) from the inlet end (32) toward the outlet end (40), the auger (88) including flights (104) having a flight wall with a radial edge, a clearance space being defined between the radial edge of the flights and the solid, imperforate wall portion (46) of the inner wall (44). Flow of fluid through the clearance space may be inhibited. One of the inner wall and the flight wall may include a perforated wall portion (48). Flow of fluid between the first auger section and the second auger section may be provided through the perforated wall portion (48).
Abstract:
A crisp food product is prepared in a first phase from thin food pieces of raw fruit, vegetable or gelatinizable proteins, by blanching them (if necessary) and drying them. A second phase takes place in a vacuum chamber, where the dried thin food pieces are exposed to heat to expand them, are quickly removed from the heat source and are cooled, before being removed from the vacuum.
Abstract:
The invention concerns a system for different types of simple or complex heat treatment of vegetable products and like, comprising a pre-heating stage, an enzymatic inactivation or cooking stage and at least a cooling stage, characterised in that each stage comprises a supply element, a conduct, within which water flows, for advancing and subjecting to treatment the product, and an element for transferring the product to the following stage, or to the exit in case of the final stage, and in that it provides a circuit for recirculation and supply of water within said conducts of each stage, provided with means for conditioning water within said conducts in function of the working in each specific stage. The invention further relates to other methods for thermal treatment or other treatments for vegetable products and like.
Abstract:
An apparatus (1) for processing fruit or vegetables using water comprises a trough (4) where processing water may be contained, a conveyor mechanism able to transport the fruit or vegetables through the processing water in a machine direction (MD), a water inlet (26) through which fresh water may be added to the trough, a water outlet (24) through which processing water may be removed from the trough. The apparatus is characterized in that the individual recirculation segments (28,29,30) are arranged in along the machine direction (MD) of the trough (4). Also fresh water inlets (26) may be arranged in the downstream end of the apparatus, such that product conveyed on the conveyor mechanism may be rinsed with fresh water as it leaves the processing water.
Abstract:
A food processing apparatus includes a tank defining an inner compartment having an inlet end for receiving food product and an outlet end for discharging food product, an open-top screen mounted within the compartment and positioned relative to the tank in a first position, and a rotatable auger mounted such that at least a portion of the auger is within the screen for advancing food product within the tank from the inlet end of the tank toward the outlet end.
