По утрам я делаю морковный сок в соковыжималке.

По утрам means in the mornings and strongly suggests a repeated, habitual action.

• утром = in the morning / this morning / in the morning generally
• по утрам = in the mornings, every morning, as a habit

So in this sentence, По утрам helps show that this is something the speaker regularly does.

It is also a fixed Russian pattern:

• по + dative plural can mean on/at such times, repeatedly
• for example:
  • по вечерам = in the evenings
  • по выходным = on weekends

So по утрам is very natural here.

Утрам is dative plural.

That is because after по in this time expression, Russian uses the dative:

• по утрам = in the mornings
• по вечерам = in the evenings

This is a set pattern, so it is best learned as a whole expression rather than trying to translate word by word.

Делаю literally means I make, and делать сок is a normal way to say make juice.

Other verbs are possible, but they have slightly different shades of meaning:

• делаю сок = I make juice
• готовлю сок = I prepare juice
• выжимаю сок = I squeeze/extract juice

Since the sentence mentions a juicer, выжимаю морковный сок would also sound very natural. But делаю is broader and very common in everyday speech.

Делаю is imperfective, which is the normal choice for a habitual or repeated action.

This sentence describes a routine:

• По утрам я делаю... = In the mornings I make...

If you used сделаю, that would usually point to a completed single action in the future:

• Я сделаю сок = I will make the juice / I’ll make some juice

So делаю is correct for a regular activity.

Both are possible, but they are structured differently.

• морковный сок = carrot juice
• сок из моркови = juice made from carrots

Russian often uses an adjective where English uses a noun modifier:

• яблочный сок = apple juice
• апельсиновый сок = orange juice
• морковный сок = carrot juice

So морковный is simply the normal adjective meaning carrot or carrot-based.

Here морковный сок is in the accusative case because it is the direct object of делаю.

• я делаю что? → морковный сок

However, because сок is a masculine inanimate noun, its accusative singular looks exactly like its nominative singular:

• nominative: морковный сок
• accusative: морковный сок

So the form does not change, even though the case function does.

В соковыжималке means in the juicer, and here it is in the prepositional case after в because it expresses location or where the process happens.

• в соковыжималке = in the juicer

Formally:

• dictionary form: соковыжималка
• prepositional singular: в соковыжималке

This is very natural in Russian. The idea is that the juice is being made in the machine.

Yes.

• в соковыжималке = in the juicer
• с помощью соковыжималки = with the help of a juicer / using a juicer

The first version focuses on the machine as the place/device where the juice is made. The second focuses more on the tool being used.

Both are understandable, but в соковыжималке is very natural for kitchen appliances.

It could be omitted.

Russian often leaves out subject pronouns when the verb ending already makes the subject clear:

• делаю already means I do / I make

So these are both possible:

• По утрам я делаю морковный сок в соковыжималке.
• По утрам делаю морковный сок в соковыжималке.

Including я can make the sentence a little clearer, more explicit, or slightly more emphatic.

No, Russian word order is fairly flexible.

The given sentence is natural and neutral:

• По утрам я делаю морковный сок в соковыжималке.

But other orders are also possible, depending on emphasis:

• Я по утрам делаю морковный сок в соковыжималке.
• Морковный сок я по утрам делаю в соковыжималке.

Starting with По утрам is very common because it sets the time frame first: As for mornings...

It is a compound-style word built from the idea of juice + squeezing.

• сок = juice
• выжимать = to squeeze out, extract
• соковыжималка = a juice-squeezer, that is, a juicer

This is a very typical kind of Russian word formation, where parts combine into one practical noun. Even though it is a long word, it is a common everyday word.
