The invention relates to a combined sterilization process of ozone, ultraviolet and nanometer silver paint films for assuring the quality of freeze-dried foods, belonging to the technical field of drying food safety control. The main processes of the combined sterilization comprise adopting nanometer silver as the raw material to pre-process the freeze-dried food, combining the sterilization method of finished products by ozone sterilization or ozone and other techniques, and controlling the microbiological content within 1000 micro-organisms / gram, coliform group bacteria (colibacillus) to reach the mark (negative). The invention adopts the mutually combined process of ozone, ultraviolet and nanometer silver, and also comprises a new process for subsequently removing residual ozone, whichnot only increases the ozone sterilization effect for leading sterilized products to control the microbiological content within the safe range, but also cannot damage the quality, the unique feature,the flavor, and the nutrition ingredients of the freeze-dried food.

The invention supplies walnut pipeline type normal temperature dryer. It ties plastic film pipe at the output of the normal temperature fan, fills the walnut into the pipe, ties the output of the filmpipe at hard outlet pipe, inserts stirring stick between the film pipe and the ground. The invention has the advantages of low investment, simple operation, easy controlling, litter powder expenditure, better flavor for dried walnut than heat drying.

The invention provides a method for preparing carboxymethyl starch sodium by the microwave non-alcohol solid phase one step alkalizing method, which makes creative improvements based on the prior dry-process production technique. The method uses micro waves to heat, thereby the reaction efficiency is high, the reaction time is short and the production efficiency is high; moreover, no dispersant is used, thereby while microwave heating, the charring of starches due to overheat does not happen, and the reaction temperature is easier to control; the alkali and chloroactic acid are both respectively added once, thereby simplifying the technological process; organic solvents such as ethanol, etc. are not used in the reaction process, thereby lowering production costs.

The invention discloses a galvanized composite brightening agent and a preparation method thereof. The galvanized composite brightening agent consists of the following components: 100-300kg / t of fatty alcohol-polyoxyethylene ether, 50-150kg / t of 95-98% sulfuric acid, 100-300kg / t of 20-40% sodium hydroxide solution, 50-90kg / t of o-chlorobenzaldehyde, 50-100kg / t of benzoic acid, 3-10kg / t of nicotinic acid, 10-30kg / t of sodium benzoate and 5-30kg / t of a nno dispersing agent; the previous components, depending on a certain sampling order and under a certain reaction condition, are prepared into the galvanized composite brightening agent. The composite brightening agent can be applicable to a potassium chlorides or sulfate galvanizing solution, and is rapid to brighten, high in cloud point, capable of remarkably widening brightness of a current density zone, bright in full gloss in a low-current density zone, and good in brightness.

The invention relates to a preparation method of a metal material surface super-hydrophobic film, and belongs to the technical field of metal material surface super-hydrophobic treatment. The method includes the steps that a metallic matrix is pretreated, and oil contamination and oxide on the surface of the metallic matrix are removed; the metallic matrix obtained after impurity removal serves as a negative electrode, a noble electrode material, a pure Ni electrode or a slicker solder alloy electrode serves as a positive electrode, the distance of the electrodes is 0.5 cm to 2 cm, the electrodes are placed into electroplate liquid to be electroplated, a direct current power source is adopted for electroplating, the electric current density is controlled to range from 50 A / dm<2> to 70 A / dm<2>, washing and blowing are carried out, and the electroplated metallic matrix is obtained; and the electroplated metallic matrix is soaked into an ethanol solution of long-chain fatty acid for 2 min or above, modification and drying are carried out, the metal material surface super-hydrophobic film is obtained, the morphology of the film is even and irregular, the roughness value is 1.732 micrometers to 2.036 micrometers, and the dewatering angle reaches 150 degrees or above. The super-hydrophobic film has the anti-sticky, self-cleaning and antiseptic performance and other performances, and is widely applied to life and industries.

The invention supplies Chinese date pipeline type normal temperature dryer. It ties plastic film pipe at the output of the normal temperature fan, fills the Chinese date into the pipe, ties the outputof the film pipe at hard outlet pipe, inserts stirring stick between the film pipe and the ground. The invention has the advantages of low investment, simple operation, easy controlling, litter powder expenditure, better flavor for dried Chinese date than heat drying.

The invention provides a nut butter processing method for a cooking machine, which includes a baking step: heating the nuts in the cup body to ripen by a heating plate; and a crushing step: driving a crushing knife to rotate by a motor to crush the nuts in the cup body. Using a cooking machine to make jam is not only more convenient and faster than the traditional home-made method, but also has fewer production steps and less utensils, making the production process easy and pleasant, which greatly improves the user's pleasure in making jam, that is, The fun of DIY for users; at the same time, the heating plate is set at the lower end of the cup body, and the heating plate includes the heating plate body and the heating tubes arranged on the side wall of the heating plate body, so that the nuts at the bottom will not be sticky, and the nuts at the bottom will not be burned from the side. Heating the nuts can make the nuts be heated more evenly, ensure that the nuts are ripe without burnt smell, and can also produce a strong nutty aroma, so that the produced nut butter is more delicious and mellow.
