Abstract

A steeping-and-filtering extraction device comprises a filter bag (2), a suspension frame (3), and a steeping container (1). An upper open corner of the filter bag (2) has four symmetrical holes (22). The suspension frame (3) has a rigid structure or a foldable structure, and an upper horizontal bar thereof has four symmetrical hanger hooks (31). The filter bag (2) is suspended from the suspension frame (3) by passing the four symmetrical hanger hooks (31) of the horizontal bar through the four symmetrical holes (22). A substance to be extracted is steeped in the steeping container (1) and then poured into the filter bag (2) for filtering.

Description

Extraction device after soaking and filtering

Technical field

The utility model relates to an extraction device which is filtered after soaking, in particular to an instrument capable of uniformly extracting and quickly filtering coffee or tea.

Background technique

With the improvement of the quality of life of modern people, instant coffee is gradually being replaced by high-quality fine coffee. It is the wish of every coffee lovers to make a delicious and delicious coffee simply and quickly. However, current coffee extraction technologies have their own advantages and disadvantages, and the technical requirements for operators are generally high, as listed below.

Hand-pulled extraction of coffee, soaking extraction and filtration of the residue at the same time, the technical requirements of the operator is high, improper operation is easy to extract insufficient or excessive extraction, poor product stability, and a variety of equipment varieties, operators are difficult to be proficient.

Siphonic extraction of coffee requires sufficient water temperature to produce hot water through the air pressure into the pot. Therefore, the water temperature is too high and the extraction is excessive. The glassware is fragile and difficult to clean, the stability of the product is poor, and the variability of the product is not much. The process is cumbersome and time consuming.

The smart cup extracts coffee, which solves the problem of step-by-step operation of soaking and filtering of hand-pulsed coffee, but the two steps use the same utensils. The shape of the utensils during extraction is not conducive to the flow of water. The speed of water is slow when filtering, affecting the coffee before and after. The consistency of the solution extraction rate, and wasted paper is not environmentally friendly.

Aile pressure extracting coffee solves the problem of filtration speed, but the pressed coffee is more turbid, the appliance structure is not durable enough, the operation is troublesome and laborious, and the service life is too short to waste resources.

The coffee hanging ear bag extracts the coffee and solves the problem of portability. It is a simple version of the hand-pulled extraction coffee, but the speed of the water is faster, resulting in insufficient extraction, and the coffee beans are pre-ground into powder and the coffee flavor is largely lost. Temperature control, steaming, fresh and nothing, coffee flavor is faint.

Summary of the invention

The purpose of the utility model is to overcome the shortcomings of the above coffee extraction method and apparatus, and to provide a coffee extraction method and apparatus which are simple in operation, stable in production, durable in appliances, environmentally friendly in consumables and portable.

The object of the utility model is realized as follows: an extraction device which is filtered after immersion, and the specific content is: It consists of a suspension frame, a filter bag and an soaking tank, and its technical solutions include.

The hanger can be designed as a fixed structure or a folded structure, and the upper beam is symmetrically provided with four hooks for fixing and hanging the filter bag.

It is particularly preferred for the hanger to be a streamlined frame structure made of metal or wood.

The bag body of the filter bag is a microporous filter structure, and has a three-dimensional cone shape formed by diamond or square. The upper open corner has four symmetric holes for fixing on the hanger.

The filter bag is particularly preferably made of a nonwoven fabric or a flannel.

The soaking cylinder is spherical or ellipsoidal, and has a diversion structure at the upper mouth.

The soaking cylinder is particularly preferably made of metal or plastic, and has a structure with a handle on the side, a high foot on the bottom, a double-layer vacuum, etc., which is convenient for taking and temperature control.

The beneficial effects of the extraction device after soaking and then filtering in the utility model are as follows: the design of the soaking tank can satisfy the uniform extraction of the coffee powder at any stable temperature; the design of the suspension frame and the filter bag can meet the needs of portability and can be quickly and cleanly cleaned. Stereo filtered coffee solution. In this way, the extraction device after the immersion and filtering can achieve the step-by-step operation of filtering the residue after immersion extraction, the water temperature and time of the extraction are controllable, the extraction is uniform, the three-dimensional filtration is fast and clean, and the filter bag for use is green and environmentally friendly.

detailed description

The structural composition of the extracting device of the present invention and the efficacies that can be produced are described in detail below with reference to the accompanying drawings.

Referring first to FIG. 1 to FIG. 7, the extraction apparatus for immersing and filtering after the present invention comprises an soaking cylinder 1, a filter bag 2 and a suspension frame 3.

among them:

The soaking cylinder 1: as shown in FIG. 6 and FIG. 7, the main body has a spherical or ellipsoidal shape, a flow guiding structure 11 at the upper end, a handle 12 on the side or a high leg 13 on the lower side.

The filter bag 2: as shown in FIG. 4, the filter bag is folded into a square shape by a rectangle along a broken line, and after the joining edge 21 is combined, as shown in FIG. 5, four fixing holes 22 are formed at a suitable position below the upper opening angle.

The hanger 3: the upper cross member is provided with four hooks 31 of the hanger corresponding to the fixing holes 22.
