α

85°。這樣保證進水刺針的射流的反射點是在料包的側壁上，使得進水刺針的射流產生更大的旋轉射流運動，使得飲料粉體溶解更加快速、更加充分，進一步提升了飲品的口感與營養價值。當α小於50°時，進水刺針的反射點不再料包的側壁上或處於料包的側壁較 低處，這樣射流產生的旋轉射流運動較小，飲品沖調效果較差；當α大於85°時，進水刺針的反射點處於料包的側壁較高處，這樣射流在側壁反射後會射向料包的膜片上，而飲料粉體都是處於料包的底壁的，導致飲料粉體不能充分溶解，造成浪費，飲品的口感不好。 3. The included angle between the jet direction of the waterjet needle and the axis of the waterjet needle is α, 50 °

α

85 °. In this way, the reflection point of the jet of the waterjet needle is on the side wall of the bag, so that the jet of the waterjet needle generates a larger rotary jet motion, which makes the beverage powder dissolve faster and more fully, which further improves the taste and Nutritional value. When α is less than 50 °, the reflection point of the inlet needle is no longer on the side wall of the bag or at a lower side of the side of the bag, so the rotary jet motion generated by the jet is small, and the effect of brewing is poor; when α is greater than 85 At °, the reflection point of the inlet needle is higher on the side wall of the bag, so that the jet will be reflected on the diaphragm of the bag after the reflection on the side wall, and the beverage powder is on the bottom wall of the bag, causing the beverage The powder cannot be fully dissolved, causing waste, and the taste of the drink is not good.

2mm，使得射流形成旋轉射流運動時，飲料粉體可以從引出刺針與料包的側壁之間穿過，不會堵在引出刺針與料包的側壁之間，避免引出刺針被飲料粉體堵塞導致料包壓力過大產生爆炸的危險，提升了使用時的安全性。當L1小於2mm時，飲料粉體容易堵在引出刺針與料包的側壁之間，可能將引出刺針堵塞，進而可能產生料包因壓力過大產生爆炸的危險。 7. The puncture hole is formed by piercing the drawn needle through the membrane, and the distance between the puncture hole and the side wall of the bag is L1, L1

2mm, so that when the jet forms a rotating jet motion, the beverage powder can pass between the pricking needle and the side wall of the bag, and will not be blocked between the pricking needle and the side wall of the bag, to avoid the pricking needle being blocked by the beverage powder. Excessive pressure in the bag creates the risk of explosion, improving safety during use. When L1 is less than 2mm, the beverage powder is easily blocked between the lead-out needle and the side wall of the bag, and the lead-out needle may be blocked, which may cause the bag to explode due to excessive pressure.

8. The needle point is formed by obliquely cutting one end of the drawn thorn needle into the material bag. The chamfered portion of the needle tip forms a chamfered surface, the chamfered surface is arranged upward, and the lead-out hole of the lancet is set on the chamfered surface so that when the jet forms a rotary jet motion, the beverage powder passes through the lancet and the package. When the side wall does not block the lead-out needle, it avoids the risk of explosion caused by the excessive pressure inside the bag; at the same time, it prevents the undissolved beverage powder from being directly discharged, thereby improving the taste of the beverage.

9. By setting the speed of the water-injection needle to 30rpm ~ 250rpm, this will not only ensure that the beverage powder can be fully dissolved and the taste of the drink is good, but also ensure the brewing efficiency, and make the drawn needle not easy to be blocked and avoid the pressure caused by the package. Risk of explosion. When the speed is less than 30rpm, the water inlet needle rotates too slowly, the beverage powder dissolves slowly, and the beverage preparation efficiency is low. Also, the drawn needle is easily blocked by the beverage powder, and the package has the danger of explosion. When the speed is greater than 250rpm, it is not safe. , Some undissolved beverage powder will be carried out from the drawn needle by the liquid flow, which will affect the taste of the beverage.

10. The method intersects the jet direction of the water-entering needle and the axis of the water-entering needle so that the water-entering needle is flushed toward the beverage powder when the liquid flow is introduced, and a driving device is added in the preparation step to drive the water-entering needle. Rotate, the water jet needle forms the jet area, and the beverage powder is washed by the liquid flow in the jet area to mix and dissolve, which accelerates the mixing and dissolution of the liquid and the beverage powder, and the beverage powder is fully dissolved without residue, which improves the taste of the beverage And nutritional value; at the same time, the waterjet needle forms a rotating jet motion during the rotation process, which better promotes the dissolution of the beverage powder and improves the brewing efficiency and taste of the beverage.

2mm。這樣設置的好處在於，引出刺針設於進水刺針正下方，便於飲品的排出；還有，引出刺針與料包的側壁之間的距離為L1，L1

2mm，這樣使得射流形成旋轉射流運動時，飲料粉體可以從引出刺針與料包的側壁之間穿過，不會堵在引出刺針與料包的側壁之間，避免引出刺針被飲料粉體堵塞導致料包壓力過大產生爆炸的危險，提升了使用時的安全性。當L1小於2mm時，飲料粉體容易堵在引出刺針與料包的側壁之間，可能將引出刺針堵塞，進而可能產生料包因壓力過大產生爆炸的危險。本實施例中，L1=4.5mm，當然，可選的L1為2mm、2.5mm、3mm、3.5mm、4mm、5mm、5.5mm、6mm、6.5mm、7mm、7.5mm、8mm、8.5mm、9mm、9.5mm、10mm等，只要 L1大於2mm即可，這裏就不再一一列舉，上述所列僅是較佳實施例而已，並非用來限定此範圍。 The lead-out lancet 5 is set directly below the water-entry lancet 4 and the lead-out lancet 5 is spaced from the water-entry lancet 4. The lead-out lancet 5 pierces the membrane to form a puncture hole. The distance between the puncture hole and the side wall of the package 7 is L1. L1

2mm. The advantage of this setting is that the lead-out lancet is set directly below the water-entry lancet, which is convenient for the discharge of the drink; moreover, the distance between the lead-out lancet and the side wall of the bag is L1, L1

2mm, so that when the jet forms a rotating jet motion, the beverage powder can pass between the lead-out needle and the side wall of the bag, and will not be blocked between the lead-out needle and the side wall of the bag, to avoid the lead-out needle being blocked by the beverage powder.

The above list is only a preferred embodiment, and is not intended to limit this range.

D

2mm，這樣設置的好處在於，能使射流產生最佳的旋轉射流運動，使得飲料粉體更快、更好的溶解，提升飲品的沖調效果。當D小於0.8mm時，會導致流量減小，不利於沖調效果，同時機器內部壓力過大，不利於密封，影響機器使用壽命；當D大於2mm時，注射孔的尺寸過大，則會導致射流的線速度減小，沖刷力下降，沖調效果變差。本實施例中，D為1.2mm，當然，可選的D為0.8mm、0.9mm、1mm、1.1mm、1.3mm、1.4mm、1.5mm、1.6mm、1.7mm、1.8mm、1.9mm、2mm。 As shown in FIG. 3 and FIG. 4, the material of the water-entering needle 4 can be plastic.

The injection hole is set on the side wall of the water-entering needle 4 that extends into the inside of the bag 7. The injection hole is circular. The hole diameter of the injection hole of the water-entering needle 4 is D, 0.8mm.

D

The advantage of this setting is 2mm, which can make the jet produce the best rotary jet motion, make the beverage powder dissolve faster and better, and improve the brewing effect of the beverage. When D is less than 0.8mm, it will reduce the flow, which is not conducive to the effect of mixing. At the same time, the internal pressure of the machine is too large, which is not conducive to sealing, and affects the service life of the machine. When D is greater than 2mm, the size of the injection hole is too large, which will cause jet flow. The linear velocity decreases, the scouring force decreases, and the scouring effect becomes worse. In this embodiment, D is 1.2mm. Of course, optional D is 0.8mm, 0.9mm, 1mm, 1.1mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm. .

The distance from the reflection point of the water inlet needle 4 to the side wall of the package 7 to the diaphragm of the package 7 is L2, the height of the package 7 is H, L2 <H, and L2 is 0.2H ~ 0.8H. The advantage of this setting is that the jet of the waterjet needle produces a larger rotary jet motion, which makes the beverage powder dissolve faster and more fully, and further improves the taste and nutritional value of the beverage; meanwhile, L2 is 0.2H ~ 0.8H In this way, it is ensured that the jet of the waterjet needle and the reflection of the side wall of the bag can generate the best rotary jet motion, so that the beverage powder is better and faster dissolved. When L2 is less than 0.2H, the reflection point of the inlet needle is not on the side wall of the bag or at a lower side of the side of the bag. In this way, the rotational jet motion generated by the jet is small, and the beverage preparation effect is poor; when L2 is greater than 0.8H At that time, the reflection point of the water-entry puncture needle is higher on the side wall of the bag. In this way, after the jet is reflected on the side wall, it will be directed to the diaphragm of the bag, and the beverage powder is on the bottom wall of the bag, which causes the beverage powder to not be fully dissolved, resulting in waste, and the taste of the beverage is not good.

The length of the water-entry puncture needle 4 protruding into the material bag 7 is L3, and L3 <L2. The advantage of this setting is that it ensures that the jet of the waterjet needle is reflected toward the bottom wall of the bag after it hits the side wall of the bag, avoiding that some of the beverage powder is washed onto the film of the bag and the beverage powder is not washed out. The body wastes and reduces the concentration and taste of the drink.
