In the drying device 10, a crushing means 20, which will be described later, And a combustion section is provided at the lower end of the crushing section 11 where the crushing means 20 is installed.

In the case of the combustion unit provided at the lower end, as will be described later in detail, the heat medium oil heated by the heat medium oil gas boiler 90 flows into the heat medium gas boiler 90 after the inside of the drying apparatus 10 is heated, .

The crushing means 20 is rotatably installed longitudinally in the crushing section 11 inside the drying apparatus 10 described above and crushes an object (food waste) charged into the drying apparatus 10 Device.

The crushing means 20 includes a main rotation shaft 21 provided in the crushing portion 11 so as to be rotatable in the transverse direction and first and second projecting portions 21 and 22 projecting in the longitudinal direction, The second shredding shaft 23 is orthogonal to the first shredding shaft 22 when the shredding shafts 22 and 23 protrude upward and downward on the outer periphery of the main shaking shaft 22 A plurality of first crushing blades 24 having an arc shape and connecting the intermediate portions of the first and second crushing shafts 22 and 23 to each other, And a plurality of second crushing blades 25 having an arc shape and connecting ends of the first and second crushing shafts 22 and 23 to each other.

The plurality of guide pieces 27 are positioned between the auxiliary crushing blade 26 and the auxiliary crushing blade 26 so that the rotation direction of the plurality of auxiliary crushing blades 26 is not changed by the guide and the turning radius position.

The primary dust filter 30 is connected to the inside or one side of the crushing section 11 of the drying apparatus 10 to primarily filter various foreign substances and dust contained in the dry steam generated in the drying apparatus 10 It plays a role.

The secondary dust filter 40 is connected to the outside of the primary dust filter 30 and the drying apparatus 10 to remove residual foreign matter and dust in the dry dust filter which are not filtered by the primary dust filter 30, . In addition, when the dry steam is filtered through the secondary dust filter 40, the condensed water generated while the heated steam is cooled is discharged to the condensate tank 80, which will be described later.

The primary dust filter 30 and the secondary dust filter 40 can be variously used by the user for the purpose of removing dust and foreign substances in the steam.

The condenser 50 condenses the inflowing steam to remove steam contained in the inflowing steam. The condensed steam is passed through the first and second dust filters 30 and 40, The condensed water generated at this time is stored in the condensate tank 80.

The condenser 50 allows the outside air to pass through a plurality of fans outside the flow tube into which the steam flows, thereby air-cooling the steam flowing inside the flow tube so that the moisture contained in the steam can be removed. : Air-cooled condenser, etc.)

The blower 60 has a structure in which steam (hot steam) having passed through the condenser 50 described above is re-introduced into the drying apparatus 10 so that the odor water vapor is recirculated, and a blower, Etc. may be used.

The buffer device 70 is a place where the uncompacted odor water vapor (increased in temperature) through the condenser 50 described above flows before entering the drying apparatus 10, (When the odorous water vapor is excessively generated and the internal pressure is excessively increased excessively), the pressure is discharged to the outside to compensate the pressure. The condensed water is discharged to the condensate tank (80).

When the condensed water is supplied to the blower 60 from the condensate tank 80 for cleaning the inside of the secondary dust filter 40 described above, when the condensed water is supplied to the buffer device 70, It may have a function of preventing the residual condensed water from flowing into the drying apparatus from such a buffer device 70 before flowing into the drying apparatus 10 again.

In other words, the odor water vapor discharged from the condenser 50 is installed in the pipeline into the drying apparatus 10, and the condensed water for cleaning the inside of the piping by the condensed water pump unit 81 is discharged to the drying apparatus 10 So that the condensed water in the access state flows back into the condensate tank and only the condensed high temperature steam is circulated to the inside of the drying apparatus 10. [

The condensate water tank 80 stores the condensed water generated in various devices connected to the drying apparatus 10 and is stored in the secondary dust filter 40, the condenser 50, the buffer device 70, etc. It is a place where the condensed water that is generated collects in one place.

In addition, some of the condensed water stored in the condensate tank 80 may be supplied to the blower 60 to be used for cleaning the inside of the piping and the blower 60, depending on the embodiment of the user.

The thermal oil gas boiler 90 is for drying the food waste which is crushed and crushed in the drying apparatus 10 described above.

The heating medium oil gas boiler 90 is heated by using gaseous fuel and then supplied to the lower end of the drying apparatus 10 through a separate inflow conduit. The high temperature (ex: 150 ° C or higher) is used to dry the food waste in the drying apparatus 10, and the used thermal oil is again introduced into the thermal oil gas boiler 90 through the discharge pipe by the thermal oil circulation pump 91 And the reheating cycle is repeated.

A flame is generated in an inner longitudinal direction (toward the lower end from the upper side) through a gas burner 90A into which gas fuel (ex .: natural gas (LNG) or the like) flows into the upper end of the thermal oil gas boiler 90 Through this flame, the heating medium tube, which is wound in a double helix inside the heating medium oil gas boiler 90 and into which the heating medium oil flows, is heated to provide the heated heating medium oil.

Of course, it is natural that a heating medium oil circulation pump 91 is installed on the pipe for the heating medium oil circulation between the heating medium oil gas boiler 90 and the drying apparatus 10. [

In addition, in order to prevent the apparatus from being damaged due to an increase in the pressure in the conduit and an increase in volume as the heat medium oil is continuously circulated in the heated state by providing the expansion tank 92 on the conduit on which the heat medium oil is circulated, So that the pressure of the expanded powder can be released to the outside.

The thermal oil gas boiler 90 may selectively use the following two control methods so that the temperature of the heat oil to be supplied by heating is maintained at a predetermined temperature range (ex. 175 ° C ± 10 ° C) at all times do.

First, the heating oil gas boiler 90, the gas burner 90A and the heating oil oil circulation pump 91 are operated to control the ON / OFF drive of the thermal oil gas boiler 90, If the heating medium oil reaches the preset temperature range (or exceeds the preset temperature range), the gas burner 90A is turned off. If the heating medium oil is out of the preset temperature range (lower than the preset temperature range) The control for turning the gas burner 90A ON and restarting is repeated.

Of course, the thermal oil circulation pump 91 must be driven at all times. In order to measure the preset temperature range, a plurality of positions (the chamber (lower portion) in which the thermal oil is stored in the drying apparatus 10, A temperature sensor is mounted on the side plate, the drying apparatus 10, the lower heating oil inlet pipe, the drying apparatus 10, and the upper heating oil oil inlet pipe). The temperature of the heating oil oil measured in the above- (For example, determining the preset temperature range based on the temperatures of the plurality of mounted temperature sensors, or determining the preset temperature range based on one of the temperature sensors), and the like.

The second is a PID control (proportional control) for controlling the gas supply amount while the gas burner 90A is always driven. The gas burner 90A is first driven to heat the heat medium oil. Unlike the first embodiment, the gas burner 90A is not turned off and is adjusted to a gas amount suitable for the present temperature before reaching the vicinity of the high value, So that the temperature of the heat medium oil can be kept constant in accordance with a predetermined temperature range. Such a second control method can maintain the temperature deviation constantly without changing greatly, thereby increasing the efficiency and reducing the gas amount.

Of these two control methods, ON / OFF drive control is suitable for small and medium-sized machines and proportional control is suitable for large machines. However, according to various embodiments of the user, This is natural.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
