The food product machine with a food supply, a rotary food pump connected to the food supply, a molding mechanism having a mold plate and a knockout drive, and a mold plate reciprocating between a fill and a discharge position. The knockout drive reciprocates a knockout plunger to discharge molded food products from the mold plate the mold plate being reciprocated between a cavity fill position and a cavity discharge position. The machine includes a manifold connected an outlet of the food pump and having an outlet passageway connected to an inlet of the molding mechanism for filling the cavity of the mold plate. The machine can further include a fill plunger system for increasing the till pressure of the food mass prior to filling the mold cavities. Plungers extend into the manifold to displace food mass volume and increase the pressure in the manifold.

The invention provides biosynthetic routes to xylitol production that do not require pure D-xylose for synthesis and that can utilize inexpensive substrates such as hemicellulose hydrolysates.
摘要:
Recombinant microorganisms are useful for producing xylitol by fermentation of arabinose. The recombinant microorganisms are produced by transformation of host microorganisms with heterologous polynucleotide sequences coding for each of L-xylulose reductase, D-tagatose 3-epimerase, and L-arabinose isomerase, which transformants express the heterologous polynucleotides at a sufficient functional level to be effective to produce xylitol from arabinose. Production of xylitol is effected by contacting these recombinant microorganisms with a substrate comprising arabinose under conditions effective to produce xylitol from arabinose.
摘要:
A food molding mechanism for a patty-forming machine that uses a servomotor to drive a crank arrangement. The crank arrangement drives a mold plate. The mechanism uses a reducer with a replaceable output shaft. The reducer engages a servomotor utilizing a double enveloping worm gear providing gear enmeshment across an arc portion of the servomotor main gear. A servomotor driven knockout apparatus comprises a cam and lever arrangement. Oil reservoirs for the knock-out cams are substantially sealed in the mold cover.

A VPN server on a radio access network may initiate a virtual private network (VPN) over a shared network, e.g., Internet, on behalf of a wireless terminal. The VPN may span the shared network, but not span the radio access network. As a result, the radio access network may be able to analyze and manipulate data sent by the wireless terminal. Additionally, the VPN may securely transport the data through the shared network.

A power supply includes a rectifier that converts an alternating current input voltage to a first direct current voltage. An inverter that converts the first direct current voltage to an alternating current output voltage. A first set of output terminals that receives the alternating current output voltage. A second set of output terminals that receives the first direct current voltage. A charging circuit that charges a backup power source based on the first direct current voltage. The rectifier receives a second direct current voltage from the backup power source based on the power supply operating in a predetermined condition.
摘要:
An automated system combines the output from multiple food product producing machines, and formatting the combined output into a format for packaging. A combining conveyor has a first lane and a second lane adjacent to the first lane. Plural food product producing machines output food products onto the combining conveyor. At least one, and preferably more than one, of the food product producing machines outputs food product into an onload position in the second lane. One or more shifting mechanisms shift the food product from the second lane into the first lane. The first and second lanes move together along a conveyor moving direction and each shifting mechanism is located downstream in a conveyor moving direction from the onload position.
