A high speed food article slicing machine with a slicing station, a moveable frame supporting a food article feed mechanism frame, a food article gate, and a safety guard system for detecting an intrusion into the machine. Food articles are loaded onto a lift tray and raised to a staging position where food articles are in contact with a food article gate. The lift tray is located inline with the food article feed paths such that lateral shifting of food articles into the feed paths is not needed. Food article grippers, individually driven along feed paths by an overhead conveyor, move food articles over the food article gate towards the slicing station. The food article gate functions to assist in removal of food article end portions. The slicing machines utilizes a horizontally radiating laser intrusion detector to shut down systems when an unwanted intrusion is sensed.

High speed slicing machine

A slicing apparatus for slicing food articles includes a food article loading apparatus with a lift tray assembly for moving food articles from a staging position to an elevated position at a beginning of a food article feed path, a food article feed apparatus disposed over the food article loading apparatus having an upper conveyor assembly with an independently driven endless conveyor belt used in cooperation with a food article gripper for moving the food articles along the food article feed path, a food article stop gate that forms part of the food article feed path and opens to drop food article end portions, and a slicing station at an end of the food article feed path with a knife for slicing the food articles.

A slicing apparatus and a weighing and classifying conveyor combination with cleanup position wherein, the elevated food article feed mechanism can be collapsed to a maintenance position, the weighing and classifying conveyor is oriented at a distance from the slicing apparatus and the slicing head cover is automatically lifted to an open cleanup position. The machine has laser intrusion detectors that are used to shut down systems when an unwanted intrusion by a person or object is detected.

Maintenance and safety system for a food article slicing machine

A food article end location detecting system for a food article slicing machine. The system includes a sensor located so that each food article passes a sensing range of the sensor as the food articles are loaded onto a food article feed apparatus. The system has instructions for calculating the length of each food article based on a location value provided by the sensor. The system also comprises a food article end disposal mechanism. The disposal mechanism has a transport for receiving said food article ends and for removing said food article ends from said food article path. The disposal mechanism also has a paddle for displacing food article ends from the transport.

Food article end detection system for a food article slicing machine

A breather air and food product fines pumping system for a reciprocating mold plate food product forming machine pumps air and fines to a collection area. A pumping surface is provided by a rearward facing surface of the mold plate. A pumping chamber is arranged between the pumping surface and a food product fines collection area. The rearward facing surface of the mold plate defines a movable limit of the pumping chamber. A valve element of a first valve is arranged between the pumping chamber and the collection area to create suction in the pumping chamber when the rearward facing surface of the mold plate is moving forward, and to allow the pumping chamber to pump air and fines into the collection area when the rearward facing surface of the mold plate is moving rearward. Breather holes in a breather plate are in communication with a breather passage that is in communication with the pumping chamber and with outside air through further valve arrangements. The further valve arrangements and the first valve act to flush the breather passage with outside air to drive air and fines in the breather passage into the pumping chamber where it is then pumped to the collection area.

Breather system for a reciprocating mold plate patty-forming machine

An improved hydraulic system is provided for a reciprocating mold plate, patty-forming apparatus wherein food product is delivered under pressure from a pump cylinder to mold plate cavities. The plunger is driven during a first phase by force from a hydraulic cylinder from a retracted position distant from the pump cylinder to a ready position initially compressing food product loaded into said pump cylinder. Thereafter, the plunger is driven during a second phase by the hydraulic cylinder to load food product under pressure into the mold plate cavities. The hydraulic cylinder is supplied with hydraulic fluid during the first phase by a low pressure hydraulic fluid pump and during the second phase by a high pressure hydraulic fluid pump. According to the invention, the low pressure hydraulic fluid pump and the high pressure hydraulic fluid pump are positioned within a reservoir, at least partially submerged in hydraulic fluid held within the reservoir, during operation. The low pressure hydraulic fluid pump and the high pressure hydraulic fluid pump are connected in series to the drive shaft of an electric motor located outside the reservoir.
