BRIEF DESCRIPTION OF THE DRAWINGS

The technical solutions and embodiments of the present invention are further described below with reference to the drawings.

Brief description of the drawings:

1 is a cross-sectional view of a brewing system having internal devices of a main system according to the present invention;

2 is an isometric view of a brewing system having internal devices of a main system according to the present invention;

Figure 3 is a detailed cross-sectional view of the tee, valve system, water tank outlet and digester inlet of the present invention; Figure 4 is a detailed cross-sectional view of the pressure control device of the present invention;

5 is a detailed sectional view of a pressure release device of the present invention;

Figure 6 is an isometric view of a fully assembled spoon system of the present invention;

Figure 7 is a sectional view of a fully assembled spoon system of the present invention.

Please refer to FIG. 1, the brewing system has a water storage tank 3.0 which can be removed or fixed as required. The water storage tank is provided with a valve joint to prevent water from flowing out of the water storage tank when the water storage tank is removed. The water storage tank can be installed at the rear, side or front of the unit, or installed in combination, or as many as required.

When the pressure / decompression device 4.0 is located as shown in the figure, the system is decompressed. When the pressure / decompression device 4.0 is located in the direction indicated by the arrow, no flow break can be passed through the bypass pipe 8.0, and the system is pressurized.

-Once the system is decompressed by the pressure / decompression device 4.0, the pressure decompression device 4.0 is manually or automatically reset to the pressurized position by electric, mechanical, pneumatic, hydraulic or a combination of the foregoing. After the system was depressurized, valve 7.0 fell to the position shown in the figure due to gravity.

Valve 7.0 is in the position shown in the figure to allow water from reservoir 3.0 to enter cooker 5.0 through tee 6.0. At the same time, the cooker 5.0 with heating elements externally or internally starts to heat the water from the water storage tank 3.0. During heating, when the pressure / decompression device 4.0 is located at the pressure position, the pressure due to heating water in the cooker 5.0 increases, causing the valve 7.0 to move upward to the tee 6.0. In this way, no water flows between the cooker 5.0 and the tee 6.0.

The pressure and temperature of the heated water in the digester 5.0 continues to increase until the pressure control device 2.0 Releases the capacity of the cooker at a set pressure. The pressure control device 2.0 can be set at a fixed pressure to brew a specific beverage, or set at a varying pressure to brew multiple beverages.

The release of the capacity of the cooker 5.0 through the pressure control device 2.0 allows pressurized water to flow through the brewing zone 1.0 to brew the required beverage. After the unit is depressurized and the unit cooker 5.0 generates enough pressure due to heating to release the pressure control device 2.0 to the capacity of the cooker, the required solids of the beverage are placed in the brewing zone 1.0.

Please refer to FIG. 3, the valve 7.0 shows the valve mechanism 7.1 in the decompression position, wherein the water in the water storage tank 3.0 can flow into the cooker 5.0 through the tee 6.0. Any water in the bypass line 8.0 will flow back to storage tank 3.0 and digester 5.0 until all points in the system are under equal pressure.

In the pressurized position, the valve mechanism 7.1 moves upward to block the flow of fluid between the tee 6.0 and the digester 5.0 due to the pressure in the digester 5.0 due to heating and the expansion of the water in the digester 5.0, By preventing any flow between the digester 5.0 and the tee 6.0, any fluid can also be prevented from entering the bypass pipe 8.0.

Please refer to FIG. 4, the pressure control device 2.0 shows the blocking mechanism 2.1 and the pressure regulator 2.2 before the pressure of the cooker reaches the set pressure. If the system needs to brew beverages under various pressures, the pressure control device 2.0 may also have a variable pressure setter 2.3.

-Once the cooker reaches the set pressure, as the blocking mechanism 2.1 moves up and the pressure regulator 2.2 length compresses, the pressure control device 2.0 releases the capacity of the cooker.

Please refer to FIG. 5, which shows that the pressure / decompression device 4.0 is in a decompression position and has a control piston 4Λ as shown in the figure. In this position, any increased pressure is released through the storage tank through the bypass pipe 8.0 until the entire system is in equilibrium and decompressed to atmospheric pressure.

When the pressurization / decompression device 4.0 is in the pressurized position, the control piston 4.1 moves in the direction indicated by the arrow, and the flow does not exist through the bypass pipe 8.0.

Please refer to FIG. 6, the brewing area shown in the isometric view is in the locked closed position, which can be represented by a formed fixing device L 1, the shape of the fixing device 1 Λ is similar to that of the spoon 1.2 and the movable filter Cover 1.3 matches. In the unlocked position, remove the movable filter cover 1.3 from the upper edge of the spoon [. 2], and remove the spoon 1.2 from the formed fixing device 1.1.

Please refer to FIG. 7, the brewing area shown in the cross-sectional view is in the locked closed position S, which can be determined by A shaped fixing device 1.1 indicates that the shape of the fixing device 1 Λ matches the spoon 1.2 and the movable filter cover 1.3. In the locked position, when the capacity of the digester is released under pressure, the water flows through the sealing device 1.4 to seal the leak-proof movable filter cover 1.3, and flows through the filter 1.5, and brews the solid matter contained in the spoon 1.2. The result is that the brewing process passes through the bottom filter 1.6 and enters the collection device through the holes 1.8.

In the unlocked position, remove the movable filter cover 1.3 and the sealing device 1.4 and the filter 1.5 from the upper edge of the spoon 1.2 without removing the spoon 1.2. When removing the spoon [2] for replenishment, use another Replace with a different or identical spoon 1.2, or to clean the fixed or removable bottom filter 1.6 mounted on the spoon 1.2, to flow out and / or replace the spoon. Any new replacement spoon will itself be fitted with a bottom filter 1.6.

In the 1.2-inch replacement spoon, you can add the solid material to be brewed 1.7 into the spoon 1.2. Put the spoon back into the formed fixing device 1.1 to return to the locked position and prepare to start another punch. The invention has been described by way of example only, and those skilled in the art can make various other modifications and / or variations without departing from the scope of the invention as defined by the appended claims.
