The invention discloses a composite slab with a symmetric structure and a manufacturing method thereof. The composite slab with the symmetric structure comprises two surface layers and core layers inside the two surface layers, wherein the core layers are formed by overlapping a plurality of layers of saw cutting plates, and each layer of saw cutting plates is adhered with each other by using an adhesive. The core layers are formed by overlapping the saw cutting plates with the thickness of 5 to 1.5 mm; a middle layer is arranged between each surface layer and each core layer and is a single plate with the thickness of 1.5-2.5 mm; the surfaces of the saw cutting plates are provided with a plurality of dot-line shaped crackles along a direction of wood grain; and the average length of the cracks is between 2.5 mm and 4.8 mm, the width is between 0.5 mm and 2.5 mm, the depth is 40 to 60 percent of the thickness of the saw cutting plates of the core layers, and the distance between the crackles is between 1 cm and 4.8 cm. The invention has the advantages of simple structure, firmness, durability, concise procedures of the manufacturing method, wide application range and easy popularization, can be used as raw materials of any panel-type furniture, and is suitable for processing and manufacturing various kinds of fast-growing tree timber composite plates.

The invention discloses a method for drying large-capacity lithium-ion power battery cells, and belongs to the technical field of lithium battery production and manufacturing. The method comprises the following steps: (1) placing the battery cell to be dried in a drying furnace, heating to raise the temperature of the furnace, and evacuating to a relative vacuum degree ≤ -99.0; (2) evacuating the vacuum to a relative vacuum degree of - 5.0~-85.0; (3) Run the blower equipment in the drying furnace to keep warm; (4) Vacuumize to a relative vacuum degree ≤ -99.0 and continue to vacuumize; (5) Sequentially perform (2), (3), (4 ) steps to cycle. The method of the invention utilizes the dry and wet hot gas convection state and the vacuum state in the furnace to dry the battery cells alternately, which can effectively reduce the moisture content of the battery cells with a small number of cycles, improve the drying rate and efficiency of the battery cells, and reduce the circulating gas Dosage and reduce calorie consumption.

The invention belongs to the field of processing of aquatic products, and particularly relates to a ready-to-eat special flavor fish product subjected to cold smoking, and a production process thereof. The production process of the special flavor fish product comprises the following steps: using freshwater fish, a composite curing agent and a compound seasoning as raw materials, cutting the freshwater fish into square blocks after scaling, killing, gill removing, gutting removing, head removing and washing, then performing vacuum rolling and curing on the blocks, using a runner to absorb moisture of the blocks to realize drying at a low temperature, performing vacuum rolling for seasoning, and performing high-temperature sterilization and other processes to obtain the ready-to-eat special flavor fish product subjected to cold smoking. According to the invention, the curing process combines the curing agent with the vacuum rolling and curing, the drying manner that the runner is used to absorb moisture to realize drying at the low temperature is combined with a way that a surface air cooler is used to cool, and the compound seasoning is combined with the vacuum rolling technology, so that not only can the curing agent, the compound seasoning and a fish body be uniformly fixed, but also the curing time, the seasoning time and the drying time are remarkably reduced, the production cost is reduced, the fish tissue is promoted to be tighter, the texture and the taste are improved, the oxidation of highly unsaturated fatty acids in the fish body can be avoided, benzopyrene can not be produced, and the quality and safety of the product can be remarkably improved.

The invention discloses a preparation method for hemp seed oil microcapsules. The preparation method comprises the following steps: (1) preparation of a wall material solution : taking maltodextrin, modified starch, Arabic gum and saccharose as main wall materials, and mixing the main wall materials and water to prepare the wall material solution; (2) sterilization: sterilizing the wall material solution; (3) emulsification: mixing and emulsifying the sterilized wall material solution and hemp seed oil to obtain an emulsion; (4) drying: spray-drying the emulsion to obtain the hemp seed oil microcapsules. The hemp seed oil microcapsules prepared by the method have the advantages of high oil content, high encapsulation rate, good stability and long quality guarantee period; the method is simple, lower in cost and conductive to practical production and application, and brings better economic benefits.
