A whole-process peanut production line and method, comprising a peanut cleaning system, a shell breaking system, a red skin removal system, a peanut kernel grading system, a superfine grinding system and a grading and packaging system. The first process is peanut cleaning and impurity removal. Peanut shell breaking is arranged behind peanut cleaning and impurity removal, peanut kernel red skin removal and peanut shell superfine grinding are respectively arranged behind the peanut shell breaking, peanut kernel grading is arranged behind the peanut kernel red skin removal, and peanut shell superfine powder grading and packaging is arranged behind the peanut shell superfine grinding.
A: An organic fertilizer for winter wheat sowing, comprising the following components in parts by mass: 90-100 parts of pine needles, 15-25 parts of chicken fat, 1-3 parts of crushed peanut stalk, 18-22 parts of an oil residue, 30-50 parts of crushed peanut shell, 40-50 parts of cereal shell, 30-50 parts of plant ash, 8-16 parts of chicken intestines, 6-8 parts of kelp powder, 20-30 parts of soybean curb residue, 60-70 parts of lard, 10-13 parts of a biological bacterium, and 150-170 parts of water.
B: A method for producing peanut oil rich in resveratrol, comprising the following steps: step I, crushing washed and dried peanut roots and mixing same with peanut kernels to obtain a mixture, wherein the mass ratio of the peanut roots to the mixture is 3-11:100; and step II, performing pressing for 15-35 min at a pressure of 25-40 MPa and a temperature of 50-70°C to obtain an oil which is peanut oil rich in resveratrol. The method for producing peanut oil rich in resveratrol does not need to add a single resveratrol product, and is suitable for industrial production.
C: A high-efficiency automated production system for walnut shell-breaking, kernel-taking and shell-kernel separation, comprising a shell breaking device (Ⅱ) which provides a squeezing member for squeezing the walnut to break shells; a kernel oscillation grading device (Ⅶ), which receives and oscillatorily grades the mixture of shells and kernels after breaking the shells, and respectively conveys to each negative-pressure vibration sorting device (Ⅵ). The negative-pressure vibration sorting device (Ⅵ) is connected to a negative-pressure separating device (Ⅳ) which absorbs and stores the shells by the negative-pressure suction force, and the kernels are classified by the negative-pressure vibration sorting device (Ⅵ) to store.
D: A peanut stem and leaf extract, a preparation method therefor and an application thereof. The peanut stem and leaf extract at least comprises naringenin-4,7&#39;-dimethyl ether, 2&#39;-O-methylisoliquiritigenin, linalool and ferulic acid. The described peanut stem and leaf extract is prepared by using the following method: pulverizing dried peanut stems and leaves to a fine powder level, and then performing extraction by using a water extraction process. The described preparation method can efficiently extract active substances from peanut stems and leaves, and the peanut stem and leaf extract can effectively improve sleep and treat insomnia.
