Abstract: A discharge chute extends between an auger and the discharge end plate of a perforated cylinder which rotates within a water-filled tank in a food processing apparatus such as a blancher or a cooler. The chute is fixed to the cylinder to rotate with the cylinder and has an inlet within the cylinder and an outlet which communicates with the exterior of the apparatus. A lifting flight extends between the perforated side wall of the cylinder and the discharge chute and is fixed to the discharge chute, such that food product advanced to the discharge end of the tank by an auger fixed to the cylinder, is engaged by the lifting flight and elevated to discharge into the chute discharge opening and then along an inclined surface within the chute to be discharged from the apparatus. The discharge assembly thus avoids any pinching of food product between rotating and nonrotating parts of the apparatus. Food product contained in pouches is protected from rupture at the discharge.

Abstract: A water tank is divided into a heated compartment and a cooled compartment by an insulated baffle. A perforated cylinder is mounted within the tank and has a first segment which extends within the heated tank compartment and a second segment which extends within the cooled tank compartment. Portions of a helical auger extend within each cylinder segment. Heated water is supplied to the heated compartment by a heated water manifold, and cooled water is supplied to the cooled compartment by a cooled water manifold. Mixing of the heated and cooled water is prevented by the insulating baffle. Food product is caused to traverse the length of the heated compartment by the auger, and is transferred over the baffle into the cooled compartment by a lifting flight which elevates food product from the water into a chute which discharges into the cooled compartment. A single, self-contained apparatus thus blanches and cools food product in a continuous process.

Abstract: A forced air oven for and a method of heating, cooking or roasting granular food, such as nuts, seeds and coffee beans. The apparatus houses a hollow cylindrical drum into which food is placed. A heated gaseous stream is forced through the inside of the drum with sufficient force to blow the food away from the inside surface of the drum.

This churning allows the heated air to envelope the outside surface of the food and provides an even transmission of heat to the food. In addition, the drum is provided with a helical fin that pushes the food toward a front end of the drum. A wire mesh is also provided for collecting particles that are dislodged from the food, and an exhaust system is provided for venting the gasses created during the heating, cooking or roasting of food.

The drum can rotate at any orientation, and the absence of a drum bearing at the undriven end permits rotational operation even when the headplate is swung open.

Abstract: A system for controlling the moisture content of moisture absorbing fruit products to achieve a uniform moisture content of the product. The continuous flow of raw product in chip, diced, extruded or comminuted form initially enters a rotating reel where the product is tumbled and exposed to a high-humidity environment for increasing the moisture content beyond a target value. The added humidity can be in the form of steam or water spray. The product continuously flows from the reel wherein moisture is added to a drying reel which reduces the moisture content of the product to specific target values. Although the original moisture content of raw fruit product entering the system may vary considerably, contact between product during mixing in the moisture adding and drying reels causes the final product to assume uniform and consistent characteristics.
