606 results about "Food process" patented technology

Food processing is the transformation of agricultural products into food, or of one form of food into other forms. Food processing includes many forms of processing foods, from grinding grain to make raw flour to home cooking to complex industrial methods used to make convenience foods.

Robust process identification and auto-tuning control

A simple yet effective and robust identification method is presented using process step responses for process identification that can provide a continuous transfer function with time-delay without iteration. A cascade relay provides accurate and reliable more points on the process frequency response. The internal model principle is employed to design single-loop controller of PID or high-order types with best achievable control performance for controller tuning, e.g. both single and multivariable cases are covered. The process identification and control design portions can be easily integrated into a control system auto-tuning package. Further, a general control scheme for disturbance rejection is given which can significantly improve disturbance rejection performance over conventional feedback systems with time delays. Practical issues such as noises, real-time implementation and tuning guidelines are also provided. The present invention provide general, systematic, effective, and applicable methods for process identification and control for a wide range of industries such as process and chemical plants, food processing, waste water treatment and environmental systems, oil refinery, servo and mechatronic systems, where a system model is needed for analysis, prediction, filtering, optimization and management, and / or where control or better control is required for their systems.

3D (three-dimensional) printing accurate forming regulation and control method for instant conditioning mashed potatoes

The invention discloses a 3D (three-dimensional) printing accurate forming regulation and control method for instant conditioning mashed potatoes, and belongs to the field of novel food processing technologies. The 3D printing accurate forming regulation and control method includes cleaning and peeling potatoes, then slicing and cooking the potatoes and mashing the potatoes until paste is delicate and bright; adding colloid into the paste, uniformly mixing the colloid and the paste with each other to obtain mixtures, and then cooking the mixtures to thoroughly cook the potatoes and sufficiently dissolve the colloid; cooling the mixtures until the temperature of the mixtures reaches the room temperature and then adding white chocolate powder into the mixtures. The 3D printing accurate forming regulation and control method has the advantages that the diameters of printing spray nozzles, the printing distances, the printing temperatures, the movement speeds of the spray nozzles and the discharge speeds are selected in order to finely print the conditioning mashed potatoes; the accuracy of printed objects can reach 95% at least, and the printed objects can be prevented from collapsing in 40-60 min after being printed; main printed materials include mashed potatoes with high usage in daily dining and can be used as desserts, snacks and the like for dining cold dish.

Pressure cooker

The invention aims at solving the problems in the prior art that food processed by pressure cookers is poor in taste, and the food processing time is long. In order to solve the problems, the invention provides a pressure cooker which comprises a cooker body with a containing cavity and a cooker cover for covering the cooker body; the cooker also comprises a stirring device and a pressure relieving device; the stirring device is arranged in the containing cavity; the pressure relieving device comprises a valve sleeve and a valve element arranged in the valve sleeve; the valve sleeve is rotatably arranged on the cooker cover and has an air outlet; a straight line, on which the air outlet direction of the air outlet is located, is not on the plane where a rotating axis of the valve sleeve is located; the pressure relieving device has an air outlet passage, one end of the air outlet passage is communicated with the containing cavity, and the other end of the air outlet passage is communicated with the air outlet; the valve element has a first position for sealing the air outlet passage and a second position for opening the air outlet passage; the valve element can move to the second position under the action of pressure in the containing cavity, or automatically return to the first position; and the valve sleeve is in driving connection with the stirring device. The pressure cooker has the beneficial effects that the processed food is good in taste and the time needed for processing food is shortened.
