Description

Technical Field

[0001] The present invention relates to the technical field of pasta preparation, and specifically to a method for preparing pasta by powdering Cordyceps militaris. Background Art

[0002] Cordyceps militaris is a fungal organism with important medicinal and health care values. It is rich in various active ingredients such as cordycepin, polysaccharides, amino acids, and trace elements, and has various physiological functions such as enhancing immunity, anti-fatigue, and antioxidant. In recent years, with the growing demand for healthy foods among people, the application of Cordyceps militaris in the field of functional foods has become increasingly widespread.

[0003] Traditional pasta, as an important part of Chinese food culture, is deeply loved by consumers for its unique taste and wide acceptance. Combining Cordyceps militaris with traditional pasta can not only expand the application forms of Cordyceps militaris, but also improve the nutritional value of pasta and develop functional foods with health care functions. However, in the actual production process, there are many technical problems to be solved when using Cordyceps militaris powder in pasta products:

[0004] First of all, Cordyceps militaris powder is a high-value-added raw material. Its texture is delicate and it has strong hygroscopicity. It is easy to agglomerate due to moisture absorption during the processing, which affects the mixing uniformity and leads to unstable product quality. In addition, due to its strong adhesiveness, Cordyceps militaris powder is easily adhered to the inner wall of the equipment, resulting in waste of raw materials, increasing the cleaning difficulty, and affecting the production efficiency.

[0005] Secondly, the active ingredients in Cordyceps militaris are sensitive to temperature. Traditional heating and drying methods are prone to inactivate the active ingredients due to excessive temperature, thus reducing its nutritional value and health care effects. How to achieve efficient dehydration without destroying the active ingredients during the production process has become a major challenge. Therefore, a method for preparing pasta by powdering Cordyceps militaris is needed to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a method for preparing pasta by powdering Cordyceps militaris, which has the advantages of uniform mixing of raw materials, precise humidity control, good particle forming, and effective protection of active ingredients, and solves the problems of poor taste of Cordyceps militaris powder pasta products and easy inactivation of active ingredients during the processing.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1.

The spiral blade promotes the feeding of raw materials during the stirring process to avoid blockage of wet materials; the water sprinkling rod realizes dynamic water addition through the spray heads adjusted by centrifugal force, and cooperates with the pressurizing piston to stabilize the water pressure, ensuring uniform distribution of moisture. This structure not only avoids waste caused by premature humidification and adhesion of Cordyceps militaris powder to equipment, but also improves the mixing efficiency of raw materials, making the combination of Cordyceps militaris and flour closer, laying a foundation for subsequent particle forming.

[0027] 2. The combined design of the heating jacket and the dehumidification mechanism in the present invention effectively balances the requirements of processing temperature and protection of active ingredients. The heating jacket accelerates the evaporation of raw material moisture through controllable indirect heating, promotes granulation, and at the same time avoids directly destroying the Cordyceps militaris active substances at high temperatures. The air duct contraction section uses the accelerated airflow to form a negative pressure, and cooperates with the fan to quickly extract water vapor and cool the particles, which not only prevents the inactivation of components caused by heat accumulation, but also shortens the particle setting time. This dual temperature and humidity control mechanism improves the processing efficiency while maximizing the retention of the nutritional value of Cordyceps militaris.

[0028] 3. The present invention optimizes the quality of granulation by combining a rotating cutter and an air flow guiding system. The cutter precisely cuts the extruded raw material during high-speed rotation, and cooperates with the air flow in the air duct to achieve instant dispersion and cooling of the particles, ensuring uniform particle size and dry surface. This synchronous cutting and cooling process design not only avoids the common adhesion problems in traditional granulation, but also makes the Cordyceps militaris particles in the final pasta remain completely visible, enhancing the visual appeal and chewing texture of the product.

[0039] Example 1

[0040] Please refer to Figures 1 - 9 , a method for preparing pasta by powdering Cordyceps militaris, comprising the following steps:

[0041] Step 1, preparation of Cordyceps militaris powder: Select artificially cultivated Cordyceps militaris fruiting bodies, wash and dry them. The dried Cordyceps militaris is processed by an ultrafine pulverizer, and the particle size is controlled to be 20-50 mesh. After sieving, uniform Cordyceps militaris powder is obtained;

[0042] Step 2, preliminary mixing of raw materials: Weigh 20-30 parts of high-gluten wheat flour, 70-80 parts of Cordyceps militaris powder, and 1-3 parts of edible salt by mass percentage, and premix them in a three-dimensional motion mixer for 5-8 minutes at a rotation speed of 15-20 rpm;

[0043] Step 3, granule preparation: Put the mixture obtained in Step 2 into a screw granulator to obtain high-gluten granules with a diameter of 1-3 mm;

[0044] Step 4, post-mixing and ripening: Put the high-gluten granules obtained in Step 3 and medium-gluten wheat flour into a double-shaft dough mixer at a ratio of 1:10, add drinking water accounting for 25-35% of the raw material weight in batches, and stir at a low speed of 60-80 rpm until the dough is formed. The dough is left to proof in an environment with a temperature of 25-30 °C and a humidity of 75-85% for 20-40 minutes;

[0045] Step 5, noodle shaving and forming: Put the ripened dough into a knife-cut noodle machine for cutting and forming.

[0046] In this method, Cordyceps militaris is prepared into large-particle debris, then prepared into high-gluten granules, and then mixed with flour to make knife-cut noodles. During the process of cooking and eating the pasta, the high-gluten Cordyceps militaris granules can be seen and eaten, greatly improving the nutritional value and taste of Cordyceps militaris.

[0047] Furthermore, the screw granulator includes a granulator main body 1 and a feeding mechanism 2, and a dehumidifying mechanism 3 is arranged on the granulator main body 1;

[0048] The granulator main body 1 includes an equipment frame 101, a feeding pipe 102, a first motor 103 and an extrusion screw 104. The feeding pipe 102 is installed on the equipment frame 101, the first motor 103 is installed at the bottom of the equipment frame 101 to drive the extrusion screw 104, and the extrusion screw 104 is installed in the feeding pipe 102 and is rotatably connected thereto;

[0049] The feeding mechanism 2 includes a feeding hopper 202, a stirring shaft 201, a second motor 203 and a water tank 204, and the feeding mechanism 2 is installed at the upper end of the feeding pipe 102;

[0050] The dehumidifying mechanism 3 includes an air duct 301 and a blower 302, and the dehumidifying mechanism 3 is installed at the end of the feeding pipe 102.

[0051] Furthermore, the feeding hopper 202 is fixedly installed at the upper end of the feeding pipe 102 and is connected thereto in a penetrating manner. The second motor 203 is fixedly installed on the upper end face of the feeding hopper 202 to drive the stirring shaft 201, and a spiral blade 2011 is arranged at the bottom of the side end face of the stirring shaft 201.

[0052] The second motor 203 drives the stirring shaft 201 to rotate, thereby driving the spiral blade 2011 to rotate. The raw materials are pushed by the spiral blade 2011, so as to control the feeding speed of the raw materials, and at the same time, it is avoided that the raw materials are agglomerated after getting wet, resulting in unsmooth feeding.

[0053] Furthermore, a water sprinkling rod 2012 communicating with the water tank 204 is arranged at the top of the side end face of the stirring shaft 201, and a scraping plate 2013 fitting with the inner end face of the feeding hopper 202 is arranged at the bottom of the side end face of the water sprinkling rod 2012.

[0054] During the rotation of the stirring shaft 201, the water sprinkling rod 2012 is driven to rotate to sprinkle water on the raw materials, increasing the humidity of the raw materials, so as to facilitate the extrusion molding of the raw materials and cutting, and at the same time, it is avoided that the raw materials adhere to the inner wall of the barrel due to pre-humidification, resulting in the residue of precious cordyceps militaris powder.

[0055] Furthermore, a spray head 2014 is arranged at the lower end face of the water sprinkling rod 2012, the distance between the spray heads 2014 gradually decreases from the edge to the center of the feeding hopper 202. A water supply channel 2018 is arranged in the water sprinkling rod 2012. A water supply pipe 2041 and a water filling pipe 2042 are arranged at the bottom of the water tank 204. A rotatably connected water supply jacket 206 is arranged at the side end face of the stirring shaft 201, and the water supply jacket 206 is connected to the water tank 204 in a penetrating manner through the water supply pipe 2041.

[0056] The water in the water tank 204 flows into the water supply jacket 206 through the water supply pipe 2041, enters the water supply flow channel 2018 through the side wall of the stirring shaft 201, and finally flows to the spray head 2014 to humidify the raw materials. The density of the spray head 2014 is proportional to the amount of the raw materials, thereby avoiding water loss or uneven water addition to the raw materials and improving the mixing effect of the raw materials.

[0057] Further, a pressurizing piston 205 with a sliding connection is arranged in the water tank 204. A connecting rod 2051 that is slidably connected to the water tank 204 is arranged on the upper end surface of the pressurizing piston 205. A limiting plate 2052 is fixedly installed on the side end surface of the connecting rod 2051, and a counterweight ring 2053 is arranged on the upper end surface of the limiting plate 2052.

[0058] Since the water flow is naturally flowing by gravity, to avoid insufficient water supply when the water flow is small, the pressurizing piston 205 is used to pressurize the water flow, so that a large water pressure can be maintained even when the water in the water tank 204 is less.

[0059] Further, a convex portion 2017 is arranged on the side end surface of the stirring shaft 201. A water inlet 2016 that communicates with the water supply flow channel 2018 is arranged at the bottom of the convex portion 2017. A shielding plate 2015 is arranged on the outside of the convex portion. A rotating shaft 20151 is arranged on the top of the shielding plate 2015. The shielding plate 2015 and the stirring shaft 201 are rotationally connected through the rotating shaft 20151.

[0060] When the second motor 203 drives the stirring shaft 201 to rotate, the shielding plate 2015 turns outwards under the action of centrifugal force, so that the water inlet 2016 is opened. The faster the stirring shaft 201 rotates, the larger the opening degree of the water inlet 2016, so that the water flow is proportional to the feeding speed, and the turning direction of the shielding plate 2015 is perpendicular to the water flow direction, avoiding excessive water pressure and causing the shielding plate 2015 to be unable to turn outwards.

[0061] Further, a heating jacket 105 is arranged on the outer end surface of the feeding pipe 102. An electric heating wire 1051 and a temperature sensor 1052 are arranged in the heating jacket 105.

[0062] The feeding pipe 102 is heated by the electric heating wire 1051, and the temperature is controlled at 45 to 55 degrees to accelerate water evaporation and promote the shaping of the raw materials. And the temperature is monitored by the temperature sensor 1052 to avoid the overheating inactivation of the active ingredients of Cordyceps militaris due to too high temperature.

[0063] Further, an air duct 301 is fixedly installed at the end of the feeding pipe 102. A contraction section 3011 is arranged in the middle of the air duct 301. An extrusion port 1021 is arranged at the end of the feeding pipe 102. The extrusion port 1021 is in through connection with the contraction section 3011. A fan 302 is fixedly installed on the top of the air duct 301.

[0064] The air blower 302 blows air downward from the top of the air duct 301. When the air flow passes through the contraction section 3011, the flow rate is accelerated, so that a negative pressure is formed at the extrusion port 1021, the water vapor is extracted, the water evaporation is accelerated, the raw material particles are promoted to form, and the air flow can quickly cool the granulated raw material, avoiding inactivation of the active substance due to heat accumulation of the raw material.

[0065] Furthermore, a third motor 303 is arranged on the side end face of the air duct 301, and a rotary cutter 3031 that fits the extrusion port 1021 is arranged on the output shaft of the third motor 303.

[0066] The third motor 303 drives the rotary cutter 3031 to rotate, so as to cut the raw material extruded by the main body 1 of the granulator. After cutting, the raw material is sucked into the air duct 301 by the air flow and discharged, and dehumidification and cooling are carried out for final shaping.

[0067] When the screw granulator is in use, first inject an appropriate amount of water into the water tank 204 through the water supply pipe 2042. The pressure-increasing piston 205 in the water tank 204 pressurizes the water under the action of the connecting rod 2051, the limiting plate 2052 and the counterweight ring 2053 to ensure stable water supply pressure. Then pour the mixed material into the feeding hopper 202, and turn on the second motor 203, which drives the stirring shaft 201 to rotate. The spiral blade 2011 at the bottom of the stirring shaft 201 pushes the raw material to the material conveying pipe 102 for feeding. At the same time, the water spraying rod 2012 at the top of the stirring shaft 201 rotates with the shaft. The water in the water tank 204 flows into the water supply jacket 206 through the water supply pipe 2041, and then enters the water supply flow channel 2018 in the stirring shaft 201, and is sprayed out from the spray heads 2014 on the lower end face of the water spraying rod 2012. The distance between the spray heads 2014 gradually decreases from the edge of the feeding hopper 202 to the center to ensure uniform humidification. When the stirring shaft 201 rotates, the baffle plate 2015 turns outwards under the action of centrifugal force to open the water inlet 2016. The faster the rotation speed is, the larger the opening degree of the water inlet 2016 is, so that the water flow is proportional to the feeding speed. After the raw material enters the material conveying pipe 102, turn on the first motor 103 to drive the extrusion screw 104 to rotate, extrude and convey the raw material. At the same time, the heating wire 1051 in the heating sleeve 105 heats the material conveying pipe 102 to 45-55 °C, and the temperature sensor 1052 monitors the temperature in real time, accelerating the water evaporation and promoting the shaping of the raw material. When the raw material is extruded to the extrusion port 1021 at the end of the material conveying pipe 102, turn on the air blower 302 and the third motor 303. The air blower 302 blows air downward from the top of the air duct 301. When the air flow passes through the contraction section 3011 in the middle of the air duct 301, the flow rate is accelerated, a negative pressure is formed at the extrusion port 1021, the raw material is extruded and the water vapor is extracted. At the same time, the third motor 303 drives the rotary cutter 3031 to rotate, cuts the extruded raw material to form particles with a diameter of 1-3 mm. The particles are sucked into the air duct 301 by the air flow, dehumidified, cooled and shaped under the action of the air flow, and finally the required cordyceps militaris high-strength particles are obtained.

[0068] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
