Abstract:
A time and energy efficient process for processing and drying fresh produce, retaining natural colour or micronutritional value is claimed. The first step comprises of enlarging the surface area of the fresh produce by at least 30% by cutting, shredding, dicing, chopping as applicable. The produce is air-dried so as to retain 30-70% of its original moisture content In the second step, the surface area of the part dried produce is further enlarged by at least 50% by cutting, shredding, dicing, chopping. The semi dried produce is air dried further so as to retain 20-50% of its moisture content. In the third and final step, remaining moisture from the semi-dried produce is removed by any known means retaining 4-20% of its original moisture content.
Abstract:
Dry Meat Savouries are prepared with powdered cereals or its flour, vegetables and- masalas. The preparation method consists of the following stages: a) Meat is dried or dehydrated in a drier at the temperature of 110° C; b) Either powdered cereals/flour or mashed vegetables in different combinations along with masalas are formed into dough; c) In drier's trays, this semi-solid dough is poured and spread as small, thin, flat round shapes. The dry meat piece is placed deep in the centre of round shaped dough pieces - so deep to be, 'seen on both sides. The trays kept inside the drier get the heat treatment at the temperature of 100° C and the products get fully and completely dried and again sun dried for 6 hours. Thus, prepared Dry Meat Savouries can be fried in oil and served for eating. The products prepared according to this method have shelf life of 4 months. Alternatively the whole process can be done under direct sun.
Abstract:
The disclosure relates to the use of electromagnetic field energy in methods and apparatus for treatment of plant products. The energy can be in the form of pulsed EMF or continuous EIVIF waves. The methods and apparatus are applicable, for example, in a variety of plant products including the treating of corn, soybeans, peas, wheat, wheat flour, and durum pasta and in a variety of industrial processes including wet and dry milling and refining operations. The methods and apparatus in particular embodiments relate to the drying of corn with potential for high energy efficiency while achieving advantageous, high quality dried corn, with a low to very low level of cracks.
Abstract:
A method for using microwave energy to accelerate freeze-drying produce having a skin that involves freezing the produce, rupturing the skin of the produce, reducing the pressure of the ruptured and frozen produce to a pressure that permits sublimation, applying a first microwave power to the produce to achieve an initial microwave power density of at least 30 W/kg, and applying a second microwave power to the produce when the produce temperature exceeds a threshold value, wherein the second microwave power is less than the first microwave power.
Abstract:
The invention relates to a method for preserving organic piece goods, for example, foods such as fruits, plants, parts thereof, small animals, and animal piece goods, and organic piece goods from the non-food sector, for example, cut flowers, using a dehydrating solvent and by drying in a drying device, and to a method for producing preserved organic piece goods. According to the invention, the organic piece goods are dried in the drying device in the presence of the solvent at temperatures below 100°C, preferably in a fluidized bed. Said procedure has the advantage of getting by with significantly lower drying temperatures compared to freeze drying, requiring substantially shorter drying times, and thus having significantly better energy efficiency, and being more environmentally friendly. A further important advantage is the gentle drying procedure, wherein the organic piece goods substantially retain the original shape, color, and contents thereof.

The present invention provides energy and economically efficient and environmentally responsible processes for using acetone to dry, dehydrate and/or dewater various hydrated feedstocks.
Abstract:
This invention relates to food processing and, in particular, blanching and dehydration of foods. Conventional blanching and dehydration requires use of steam and forced hot air. This invention is the first to effectively use infrared radiation energy to perform simultaneous blanching and dehydration of fruits and vegetables. Since this technology does not involve the addition of steam or water in the process of blanching, it has been named “infrared dry-blanching” (IDB) technology. IDB is intended to be a replacement for current steam, water and/or microwave blanching methods. It can be used to produce many kinds of value-added dried, refrigerated, frozen and dehydrofrozen foods such as fruit and vegetable products. In general, the advantages of IDB include (1) uniform heating which enhances energy efficiency and limits damage from over-heating, (2) capability of zone heating to address differential density, (3) ability to treat large or small lots with the same piece of equipment, (4) portability, since equipment can be built on wheels, and (5) a safe, non-toxic process with no harmful side-effects to humans or the environment.
