In a displacement metering pump, comprising a cylinder housing, which has a product inlet and a product outlet and in which a sealed displacement piston can be moved back and forth, wherein the cylinder housing, with a piston rod seal fixedly installed therein for the displacement piston forming a piston rod and with the placement of the product inlet and the product outlet, has no dead space and is self-emptying, i.e. can be flawlessly cleaned with respect to CIP hygiene.

The present invention concerns an apparatus and method utilizing a crimping roller which itself comprises a plurality of radially extending separating blades, with each blade comprising a central triangular cutting edge and two sealing portions extending from opposing sides of the base of the triangular cutting edge.

The present invention relates to a spring roll making apparatus comprising: a supply part for supplying rice paper; a moving part for moving the rice paper supplied by means of the supply part; a softening part for inducing softening of the rice paper moving by means of the moving part; a feeding part for feeding a filling onto the rice paper softened by means of the softening part; a folder part for folding the rice paper on which the filling is put; and a rotating part for rolling the rice paper folded by means of the folder part, and thus spring rolls can be mass-produced.

The present invention provides a soft material forming apparatus, which comprises a forming mold assembly and a detaching assembly. The forming mold assembly comprises a first roller and a second roller, for extruding a product. There is a specific interval between the detaching assembly and the first roller. The product comprises a release portion which is the earliest part of the product that contacts the detaching assembly. With the specific interval and the rotatability of the detaching assembly, the product can be released from the forming mold assembly.

A stuffing and molding mechanism of a dough food product processing machine includes a stationary structure inside which first and second mold rollers are arranged. At least one demolding rotary disc includes a disc body formed with a shaft hole by which a retention key is provided. The demolding rotary disc is fit to an end of a molding cutter of one of the mold rollers by means of the shaft hole for synchronous rotation therewith. At least one demolding pawl is raised from one side of the disc body that is adjacent to the molding cutter. A tubular dough skin filled with stuffing is supplied between the two molding cutters to be pressed and cut and then sealed to form a dumpling. Demolding of the dumpling is achieved by having the demolding pawl that is provided on the demolding rotary disc contact and push one side of the dumpling.

A stuffing filling and gas charging system of a dough food product machine is arranged between a stuffing feeding unit and a dough feeding unit of the dough food product machine and includes a stuffing conveyance pipe, and a shaft sleeve, a dough driving rod, and a screw rod support enclosure sleeved over the stuffing conveyance pipe. A first passage is formed between the shaft sleeve and the stuffing conveyance pipe; a second passage is formed between the dough driving rod and the stuffing conveyance pipe; and a third passage is formed between the screw rod support enclosure and the stuffing conveyance pipe. The passages are in communication with each other and are connected to a gas supply unit, so that air flow is introduced into a dough skin during the dough skin being shaped to prevent the dough skin from wrinkling and collapsing before being properly shaped.

A device for roiling up flat dough around or without a filling to produce a rolled food product is comprised of: a first belt having an end and moving in a first direction toward the end to convey the dough with or without the filling laid on the first belt; a second belt so disposed adjacent to the end as to make the dough conveyed in the first direction be brought into contact with the second belt to curve the dough and movable in a second direction perpendicular to the first direction; and holding members arranged along the first belt to guide the dough curved along the second belt around along the holding members, whereby rolling up the dough.

A feeding unit for feeding a food product for a machine for making filled pasta includes at least one feed duct having an outlet and an inlet; a sleeve fitted coaxially over the duct and rotatable relative thereto about an axis of rotation R in order to regulate the cross section of the inlet; an actuator including a stem inserted in the sleeve and movable between a first, retracted operating position and a second, extracted operating position to allow the food product to enter the feed duct and to push at least one single portion of food product out of the duct through the outlet; a second sleeve, fitted between the first sleeve and the stem, the stem sliding inside the second sleeve and the first sleeve rotating on the second sleeve.
