Description

Technical Field

[0001] This application relates to the field of coffee brewing equipment, and more particularly to an integrated coffee brewing system. Background Technology

[0002] Traditional coffee brewing techniques primarily rely on drip brewing, espresso extraction, or cold brewing. The core equipment typically depends on metal heating modules or enclosed boiler structures, transferring heat through conduction or convection. However, these techniques have limitations: firstly, the metal material can lead to a monotonous coffee flavor, lacking the integration of natural aromas; secondly, existing equipment is incompatible with non-traditional containers, hindering the integration of flavor innovation with traditional cultural elements. In recent years, some attempts have attempted to heat non-metallic containers using external heat sources (such as open flames or electric ceramic stoves), which can introduce natural aromas, but these solutions suffer from uneven temperature control, low thermal efficiency, and complex operation. Summary of the Invention

[0003] To address or partially address the problems existing in related technologies, this application achieves a three-dimensional uniform heat field distribution through external tube radiative heating combined with cavity convection design, avoiding the problem of coffee burning and bitterness caused by local overheating. In addition, the inner wall of the bamboo tube releases natural bamboo fragrance substances (such as bamboo olefins and phenolic compounds) during the heating process, which work synergistically with coffee oils and aromatic components to form a unique complex flavor. At the same time, the microporous structure of bamboo fibers can absorb coffee impurities and improve the purity of the taste.

[0027] Currently, on the one hand, metal materials tend to result in a monotonous coffee flavor and a lack of natural aroma blending; on the other hand, existing equipment is difficult to use with non-traditional containers for coffee brewing, making it impossible to achieve flavor innovation and the integration of traditional cultural elements.

[0028] To address the aforementioned issues, this application utilizes an external tube radiant heating system combined with a cavity convection design to achieve a three-dimensional uniform heat field distribution, avoiding the problem of coffee burning and bitterness caused by localized overheating. Furthermore, the inner wall of the bamboo tube releases natural bamboo aroma substances (such as bamboo olefins and phenolic compounds) during the heating process, which work synergistically with coffee oils and aromatic components to form a unique complex flavor. At the same time, the microporous structure of bamboo fibers can absorb coffee impurities, enhancing the purity of the taste.

[0029] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0030] See Figure 1-3 The first aspect of this application provides an integrated coffee brewing system, including a base 1, an outer tube 3, a bamboo tube 10, and an electric heating element 7. In this embodiment, the base 1 has an inclined platform structure. The outer tube 3 is inclinedly installed on the base 1 via a bearing seat 2. The outer tube 3 forms an inner cavity 9, and an opening is provided at the head position of the inclined high side. The bamboo tube 10 is inserted into the outer tube 3 along the opening. The electric heating element 7 is located at the bottom of the outer tube 3 for heating it and transferring heat to the bamboo tube 10. The electric heating element 7 is connected to a temperature control switch 8. Specifically, the base 1 is made entirely of stainless steel and has an inclined platform structure with a lower front and higher back. The inclination angle is 15° to 25° (preferably 20°). A liquid collection tank is provided at the lower end of the inclined platform for collecting liquid overflowing during the brewing process. An anti-slip rubber pad is fixed to the bottom of the base 1, and the bearing seat 2 is fixed to the top with bolts. The outer tube 3 is a high-temperature resistant alloy steel pipe with an inner diameter slightly larger than the outer diameter of the bamboo tube 10 (gap 0.5 to 1 mm). It is inclinedly installed on the base 1 via the bearing seat 2, consistent with the inclination direction of the base 1. An opening (202) is made at the head of the outer tube 3. The bamboo tube 10 is made of natural bamboo segments with a diameter of 80-100mm, retaining the nodes at both ends. Holes are pre-drilled at the top node to form a water inlet and a coffee inlet. The heating element 7 uses a spiral nickel-chromium alloy heating wire, embedded in a groove on the inner wall of the bottom of the outer tube 3, and is insulated by a ceramic insulation layer. The heating element 7 is connected to a PID temperature control switch 8, with a temperature control range set to 85-95℃ and an accuracy of ±1℃.

[0031] Specifically, in other embodiments, a rotating mechanism is also connected to the outer tube 3. The rotating mechanism includes a motor 4 and a gear transmission mechanism. The motor 4 is mounted on the base 1. The motor 4 is a 24V DC geared motor and is fixed to the inclined lower side of the base 1 by a bracket. The gear transmission mechanism includes a driving gear 5 mounted on the drive shaft of the motor 4 and a driven gear 6 mounted on the outer tube 3. The driving gear 5 and the driven gear 6 mesh with each other. After they mesh, the outer tube 3 rotates at a constant speed of 5 to 10 r / min.

[0032] Specifically, a push rod 11 is installed at the bottom of the outer tube 3 to push out the bamboo tube 10 after heating is completed. Specifically, the telescopic end of the push rod 11 is connected to a push plate, and the surface of the push plate is covered with a silicone layer to avoid scratching the bamboo tube 10. A heat insulation cover 12 is covered on the base 1 to keep the heating element 7 warm during the heating process of the outer tube 3. Specifically, the heat insulation cover 12 adopts a double-layer hollow fiberglass structure and covers the base 1. The cover has an observation window and an exhaust hole.

[0033] In other embodiments, such as Figure 2 As shown, this technical solution uses three sets of outer tubes 3 arranged together, each equipped with driven gears 6 meshing with each other. After being driven by the motor 4, the three sets of outer tubes 3 can be driven to rotate simultaneously at one time. In the specific implementation process, the number of outer tubes 3 can be increased or decreased during the manufacturing process according to the user's needs. For products suitable for home use, 1-3 sets of outer tubes 3 can be designed. If it is necessary to adapt to the needs of standardized commercial scenarios, it can be increased to 5-10 sets for use by merchants with high traffic.

[0034] After inserting the bamboo tube 10, coffee and water are injected through the water inlet. The heating element 7 is activated to heat to the set temperature. The insulation cover 12 is closed, and the motor 4 is activated to drive the outer tube 3 to rotate. During the heating process, the bamboo tube 10 rotates with the outer tube 3 to ensure that the coffee liquid is heated evenly. After the brewing is completed and the temperature drops to the safe threshold, the push rod 11 is pushed to push out the bamboo tube 10. The user can then take it out after confirming the status through the observation window.

[0035] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
