What is the relationship between aspirin and plant?
Plants produce salicylic acid , and it makes sense how aspirin helps plants, because aspirin is so similar to salicylic acid (which naturally is a process that occurs in plants)
adding dissolved aspirin to plants can cause the same immune response as an infection ,intentionally triggering the plant to strengthen itself
How aspirin produce? Raw Materials The Manufacturing
Process1.Weighing2.Mixing3.Dry screening4.Compression5.Testing6. Bottling and packaging
Raw Materials: To produce hard aspirin tablets, corn starch and water
are added to the active ingredient (acetylsalicylic acid) to serve as both a binding agent and filler, along with a lubricant.
lubricant is added during mixing (hydrogenated vegetable oil, stearic acid, talc, or aluminum stearate).
aspirin tablets contain different diluents, such as mannitol, lactose, sorbitol, sucrose
( which allow the tablet to dissolve at a faster rate and give the drug a pleasant taste)
The Manufacturing Process
Aspirin tablets are manufactured in different shapes. Their weight, size, thickness, and hardness the tablets may be flat, round, concave, or convex to various degrees. The tablets may also have a line scored down the middle of the outer surface.
Weighing
The corn starch and the lubricant are weighed separately in sterile canisters to determine .
Mixing
By machine called a Glen Mixer Mixing blends the ingredients as well as expels air from the mixture. mechanically separated into units its called slugs.
Dry screening
small batches of slugs are forced through a mesh screen by a hand-held stainless steel spatula
Compression This drawing illustrates the principle of compression in a single-punch machine. First, the aspirin mixture is fed into a dye cavity. Then, a steel punch descends into the cavity and compresses the mixture into a tablet. As the punch retracts, another punch below the cavity rises to eject the tablet
Testing see Quality Control section below
Bottling and packaging The tablets are transferred to bottling assembly line dispensed into clear or color-coated polyethylene or polypropylene
plastic bottles or glass topped with cotton packing, sealed with a sheer aluminum top serves as an additional seal to discourage and detect product tampering. labeled with product information , expiration date , then packaged in individual cardboard boxes. then boxed in larger cardboard boxes in preparation for distribution to distributors.
