ACCUMULATOR

A hydraulic device charged with dry nitrogen and acts to control the hydraulic shock to a system.

ACCUMULATOR PRE-CHARGE

The pressurized gas which is placed in an accumulator. The accumulator must be completely drained of hydraulic pressure before pre-charging with dry nitrogen.

BREATHER PLATE

The precision ground plate that is installed above the mold plate that allows the air to escape from the mold plate through several small holes.

BREATHER TUBE

A tube that connects the top of the mold cover to the hopper front through which excess product is returned to the hopper.

CUSHION

A devise that restricts the flow of hydraulic fluid in order to slow the movement of a hydraulic actuator at the end of its stroke.

DIRECTIONAL CONTOL VALVES

Hydraulic and pneumatic valves that control the direction of flow in the system.

FEED SCREWS

Auger-type devices located inside the hopper that move product forward to the pump box.

FILL SLOT

The filling orifice that is installed under the mold plate.

FLOW CONTROL VALVE

A mechanism used to adjust the operating speed of a hydraulic actuator.

FORM-FILL

A fill technique primarily used for premium whole muscle forming.

HOPPER

The part of the machine where product is placed and held prior to filling the mold plate.

KNOCKOUT CUP

A devise that extracts the formed product form the mold plate.

KNOCKOUT HEATER

A heating devise used to warm the knockout cup in order to aid in the release of the formed product from the knockout cup.

MOLD COVER

Movable part of the machine that can be raised and lowered to permit access to the mold plate for installation and replacement. The knockout assembly is attached to the mold cover.

MOLD PLATE DRIVE CYLINDER

A hydraulic cylinder which provides the reciprocal motion to the mold plate. This cylinder has internal cushions on both ends that are non-adjustable.

MOTOR ROTATION

The rotation of a motor (clockwise or counter-clockwise) can be determined by looking at the drive end of the motor.

OIL COOLER

A conditioner that utilizes flowing water to cool hydraulic oil.

PLUNGER

A hydraulically driven cylinder that moves product through the pump box.

PNEUMATIC LOCKOUT VALVE

Lockout valves exhaust downstream pressure and can be locked in the shut-off position using a padlock.

PORTION-FORM

A fill technique primarily used for the larger pieces or whole muscle pieces.

PRODUCT PRESSURE

The pressure applied to product in order to produce a formed patty.

PROXIMITY SWITCH

An electrical switch that is able to detect the presence of nearby objects without any physical contact.

PUMP BOX

The part under the hopper where product is forced by the plunger to move it to the fill plate.

RELIEF VALVES

Hydraulic and pneumatic valves used to protect a system from high pressure or to limit the amount of pressure available to a component.

SOFT-FILL

A fill technique primarily used for ground product patties with a premium texture.

SOLENOID

An electrical device that activates directional control valves.

SOLENOID CONNECTOR LIGHT

The neon lights inside the connectors that attach the hydraulic directional valve solenoids to the electrical system and show when power is activated to the solenoid.

STRIPPER PLATE

A device that cuts interwoven product fibers in the Soft-Fill fill plate.

TRAVERSE (OR PLUNGER TRAVERSE)

The movement of the plunger when it is not actually filling the mold plate with product.
