[0032] 2. Pellet making machine: polishing machine (pan pill method).
[0033] 3. Screening equipment: 80-mesh standard medicine sieve (rough processing), (100-mesh standard medicine sieve is used for fine processing of 70% wolfsbane ratio group).
[0034] 4. Mixing container (mixing barrel): food grade stainless steel barrel (capacity ≥ 50L).
[0035] 5. Weighing tool: electronic scale (accuracy 0.01kg).
[0036] 6. Water adding device: air pressure water sprayer.
[0037] 7. Protective equipment: N95 mask, goggles, rubber gloves (wolfsbane is a poisonous plant, protection is required throughout the operation).
[0038] Figure 1 The flow chart of the preparation method of rodenticide prepared by using wolfsbane is shown in the figure. Figure 1 As shown, the preparation method of the rodenticide prepared by using wolfsbane of the present invention comprises the following steps:
[0039] 1. Prepare coarse powder.
[0040] The dried rhizomes of wolfsbane were put into a grinder for pulverization, and then filtered through an 80-mesh sieve to obtain a coarse powder.
[0041] 2. Premix.
[0042] The coarse powder and the auxiliary material powder are poured into a mixing barrel and premixed to prepare a mixed powder. The auxiliary material powder is prepared by premixing highland barley flour and wheat flour in a mass ratio of 1:1.
[0043] The premixing is manual premixing and the premixing time is 5 minutes.
[0044] In the present invention, two rodenticides with different contents were prepared, namely a 30% group and a 50% group. The materials used for these two rodenticides with different contents are as follows:
[0045] Group Wolfsbane ratio Dosage of wolfsbane powder (kg) Barley + wheat flour dosage (kg) Total amount (kg) 30% group 30％ 6.35 14.82 21.17 50% group 50％ 14.80 14.80 29.60
[0046] 3. Prepare the basic pellet core.
[0047] The mixed powder is put into the drum of a polishing machine, purified water is sprayed into the drum, and the powder is rolled at a constant speed to form a basic pellet core with a diameter of 1.5-2 mm.
[0048] The purified water is 25° C. water and 5 ml of purified water is sprayed each time. In addition, the mass ratio of the mixed powder to purified water is controlled to be 78:22 to 75:25.
[0049] Specifically, for the 30% group, the mass ratio of the mixed powder to purified water was 78:22. For the 50% group, the mass ratio of the mixed powder to purified water was 75:25.
[0050] Furthermore, in the present invention, in order to facilitate the preparation of the basic pellet core, the premixing time is set to 8 minutes.
[0051] 4. Prepare wolfsbane pills.
[0052] The mixed powder is placed in a polishing machine, the basic pill core is added, and purified water is sprayed, and the mixture is stirred while spraying to form uniform pills to prepare wolfsbane pills.
[0053] The purified water is 25° C. water and 5 ml of purified water is sprayed each time. In addition, the mass ratio of the mixed powder to purified water is controlled to be 78:22 to 75:25.
[0054] Specifically, for the 30% group, the mass ratio of the mixed powder to purified water was 78:22. For the 50% group, the mass ratio of the mixed powder to purified water was 75:25.
[0055] In the present invention, when preparing the wolfsbane pills, water is added while stirring for 10 minutes to form uniform pills.
[0056] Figure 2 The flow chart of another method for preparing rodenticide using wolfsbane is shown. Figure 2 As shown, the preparation method of the rodenticide prepared by using wolfsbane of the present invention comprises the following steps:
[0057] 1. Prepare coarse powder.
[0058] The dried rhizomes of wolfsbane were put into a grinder for pulverization, and then filtered through an 80-mesh sieve to obtain a coarse powder.
[0059] 2. Prepare fine powder.
[0060] The obtained coarse powder was filtered through a 100-mesh sieve to obtain fine powder.
[0061] 3. Premix.
[0062] The fine powder and auxiliary material powder are poured into a mixing barrel and premixed to prepare mixed powder. The auxiliary material powder is prepared by premixing highland barley flour and wheat flour in a mass ratio of 1:1.
[0063] The premixing is manual premixing and the premixing time is 5 minutes.
[0064] In the present invention, 70% group of Langdu Pills is prepared, so the mass ratio of the fine powder to the auxiliary material powder is 7:3.
[0065] 4. Prepare the basic pellet core.
[0066] The mixed powder is put into the drum of a polishing machine, purified water is sprayed into the drum, and the powder is rolled at a constant speed to form a basic pellet core with a diameter of 1.5-2 mm.
[0067] The purified water is 25°C water and 5 ml of purified water is sprayed each time. In addition, since the fine powder contains less fiber, the amount of water needs to be reduced to prevent excessive stickiness. Therefore, the mass ratio of the mixed powder to purified water is controlled to 82:18, that is, 18% water is used.
[0068] Furthermore, in the present invention, in order to facilitate the preparation of the basic pellet core, the premixing time is set to 8 minutes.
[0069] 5. Prepare wolfsbane pills.
[0070] The mixed powder is placed in a polishing machine, the basic pill core is added, and purified water is sprayed, and the mixture is stirred while spraying to form uniform pills to prepare wolfsbane pills.
[0071] The purified water is 25°C water and 5 ml of purified water is sprayed each time. In addition, since the fine powder contains less fiber, the amount of water needs to be reduced to prevent excessive stickiness. Therefore, the mass ratio of the mixed powder to purified water is controlled to 82:18, that is, 18% water is used.
[0072] In the present invention, since fine powder is not easy to stir uniformly, it is necessary to extend the stirring time. Specifically, to prepare Langdu Pills, water should be added while stirring for 15 minutes to form uniform pills.
[0073] The above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications based on the above description are possible. It is not possible to enumerate all embodiments here. Any obvious variations or modifications arising from the technical solutions of the present invention remain within the scope of protection of the present invention.
