An improved processing method and system for producing tomato paste and other food products affected by viscosity. Tomatoes are processed into tomato juice. The juice is provided to a decanter that separates or fractionates the juice into two portions—a thicker, more viscous cake portion and a thinner, less viscous serum portion. The serum portion is concentrated by removing a portion of water using an evaporator such as a thin film or juice evaporator. The cake portion can be concentrated if necessary with a drier. The serum and cake portions are recombined to produce a tomato paste having improved color, texture, flavor and nutrition.

The invention relates to a filter device installed at the air inlet of a self-ventilation motor, and in particular relates to an air-intake and filter device of a motor. The air-intake and filter device of the motor comprises a shell taking the shape of an arc, wherein one side of the shell is provided with an air inlet, the lower part of the shell is provided with an air outlet, and a protection cover is arranged on the air inlet; a dust collection groove with an open upper part is arranged in the shell close to the air outlet, and the dust collection groove is separated from the air outlet through a partition fixed among the inner wall of the shell, the dust collection groove and the air outlet; a lower air deflector is arranged above the partition, the air inlet of the shell stretches inwards to be provided with an upper air deflector which takes the shape of an arc and fits with the arc-shaped shell, an air intake channel is formed between the upper air deflector and the inner wall of the shell, and the lower end of the upper air deflector is positioned above the lower air deflector and has a gap with the same; a dust removal opening is arranged on the dust collection groove. The air-intake and filter device of the motor is simple in structure, small in wind resistance, easy to maintain, convenient to maintain and greatly saved in cleaning and maintaining costs, and can be widely applicable to filtering dust of the self-ventilation motor.

A shell-and-tube heat exchanger capable of conveniently cleaning a shell pass is composed of an end socket, an end socket flange, a tube sheet, a heat exchange tube, a shell, a spraying pipe spacer, a baffle plate, pollution discharge nipples, a support and the like. The shell-and-tube heat exchanger capable of conveniently cleaning the shell pass is characterized in that a plurality of pollution discharge nipples are designed at the bottom of the shell, and a spaced rod in an existing technology is replaced by the spraying pipe spacer. When a cleaning operation is needed, blind plates of the pollution discharge nipples are dismounted, pollution discharge water pipes are connected, the end socket is dismounted, an end cap of the spraying pipe spacer is screwed off, a high-pressure water pipe is connected, and cleaning can be carried out by filling high-pressure water. Sewage after being cleaned is collected into a high-pressure cleaning machine through the pollution discharge water pipes, the sewage is recycled after filtration treatment to reduce or avoid the pollution on surroundings. According to the shell-and-tube heat exchanger capable of conveniently cleaning the shell pass, the problem that a shell pass of a common shell-and-tube heat exchanger is cleaned difficultly is solved, the shell-and-tube heat exchanger capable of conveniently cleaning the shell pass has positive significance that use efficiency of the shell-and-tube heat exchanger is improved, washing and maintaining cost are reduced, and the service life is prolonged. According to the technical scheme, the shell-and-tube heat exchanger capable of conveniently cleaning the shell pass is suitable for fixing various shell-and-tube heat exchangers which are of a shell-and-tube type, a floating-head type, a U-shaped-tube type and the like.

The invention discloses an integrated system of pressurized water pumping and irrigation for deep foundation pits in water-rich and iron-rich areas and a construction method. One side of the two telescopic rods is fixedly provided with two telescopic rods, one end of the two telescopic rods is fixedly provided with a support pad, and one side of the support pad is fixedly provided with a servo motor. The invention adopts the sealed depressurization well to extract the pressurized water within the scope of the foundation pit, and refills the mined pressurized water to the bearing outside the foundation pit through the integrated system of pumping and irrigation of the deep foundation pit in water-rich and iron-rich areas. In the pressurized aquifer, the invention not only reduces the impact on the surrounding environment, but also effectively avoids the frequency of operation failures such as pipeline blockage caused by the production of iron ion colloid, reduces the cleaning and maintenance costs of later operation, and greatly improves Work efficiency, at the same time has significant economic benefits and environmental protection effects.

The invention belongs to the technical field of coatings and discloses high-gloss and friction-resistant varnish and a preparation method thereof. The varnish is prepared from raw materials as follows: tung oil, linseed oil, cera alba, rosin modified phenolic resin, mineral oil, gel, a drying agent and an antioxidant. The varnish has the characteristics of good friction resistance, high gloss and proneness to drying, and the preparation process of the varnish has the advantages of being convenient to operate, low in cost and suitable for large-scale industrial production.
