Method for preparing whey protein powder (WPC) and lactose powder simultaneously by whey

The invention belongs to a production technology of a dairy product and particularly relates to a method for preparing WPC and lactose powder simultaneously by whey. The main steps are as follows: (1) primary ultrafiltration: a whey solution passes through an ultrafiltration membrane with the molecular weight cutoff of 5,000 to 10,000Da; (2) moisturization and ultrafiltration: when the membrane flux is reduced to 60% to 80% of the primary membrane flux, continuously supplementing 2 to 5 times of deionized water based on the volume of a concentrated solution into the concentrated solution to obtain a permeate and the concentrated solution; (3) preparing the whey protein powder: ultrafiltrating and drying the whey protein powder to obtain the WPC; and (4) refining the lactose powder: adding the evaporated and condensed ultrafiltration permeate into food grade ethanol till the final volume fraction is 40 to 60%, collecting, washing and drying the precipitate to obtain the lactose. According to the method for preparing the WPC and the lactose powder simultaneously by the whey, WPC with high protein content and lactose powder with high purity are obtained simultaneously through the ultrafiltration as a main separating method, and the deionized water and the food grade ethanol are only added in the whole process but the substances including external salt, acid and alkali and the like are not added.

Small-caliber and variable-aperture grid assembly

The invention discloses a small-caliber and variable-aperture grid assembly. The target of prolonging the service life of an ion thruster is achieved by improving the beam extraction uniformity and prolonging the service life of the grid assembly. An accelerating grid in the grid assembly is uniform in diameter; an opening region of a screen grid is divided into a plurality of regions with different pore diameters; the pore diameters are sequentially increased progressively from small to large from the center region to the edge region, so that the beam extraction in the center region is suppressed and reduced; and the beam in the edge region is increased to improve the beam uniformity. Due to the reduction of the beam in the center region, charge exchange ions in the region can be effectively reduced, so that sputtering corrosion to the region of the grid assembly caused by the charge exchange ions is reduced, and the service life of the grid assembly is prolonged.

The invention relates to the technical field of a condensing agent, and especially relates to applications for using medium-chain fatty glyceride as a condensing agent in dropping soft capsule or capsules. The medium-chain fatty acid is glyceryl caprylate-caprate. The glyceryl caprylate-caprate is short in carbon chains, and has very good compatibility with various kinds of solvents, grease, additives, vitamins, and other substances. The content of unsaturated fattyacid of the medium-chain fatty glyceride is very low, and oxidation stability is good, so service life of a condensing agent can be effectively prolonged. In addition, after the capsules are finished to drop, an organic solvent can be used, for example, ethyl alcohol, to remove grease on the surface of a raw product. The method solves problems in the prior art that grease can be wiped just by conventional gauze and oil-absorbing sheets, and oil removing is not thorough.

Apparatus and method for continuous stretch forming of aluminium plastic membrane

InactiveCN103660270AImprove liquidityConducive to supplementary extensionFront edgeLithium-ion battery
The invention provides an apparatus and a method both for continuous stretch forming of an aluminium plastic membrane. Two edge-pressing strips on a conventional stretch mold are removed and a cutting device is arranged. A notch is formed at the front edge of the aluminium plastic membrane subjected to stretch forming and in the direction perpendicular to the aluminium plastic membrane conveying direction by utilizing the cutting device. Because the edge-pressing strips, which are used to tightly fixing the aluminium plastic membrane, do not exist during stretch forming, a template cannot fully fix the aluminium plastic membrane, so that the flow and the supplement extension of a material at the front-edge notch of the aluminium plastic membrane are generated, and the aluminium plastic membrane is fully uniformly stretched, thus an shell prepared from an aluminium plastic membrane possesses enough strong barrier property and the risk of generating product quality problems in the usage process of an lithium ion battery is reduced. Also, because the front-edge notch of the aluminium plastic membrane helps to supplement the aluminium plastic membrane, the edge needing cutting of the formed aluminium plastic membrane is reduced, and the waste of the raw material is reduced. Because no edge-pressing strips are arranged on the stretch mold, the problems are avoided that the manufacture and the process of the mold are complex caused by the arranging of the edge-pressing strips.
